As far as the image itself goes, we have enough detail to offer a variety of different elements, but not making the scene a crowded, jumbled mess. The only spot which maybe could have used more was the upper corner, but as the moon is there, it seems to represent a clear night sky, so it’s not as big a deal. Something I didn't notice until later was the line thickness around Espurr, where it gets thicker as the light increases. Interesting effect, giving the illusion of dark contrast behind the body. The focus here is quite clear, with the pokemon both being centered and very prominently featured in its action, and the shading of the image assists in bringing the eye to the focus. A few of the tree branches also point toward Espurr, which allows the eye to naturally curve back to it.
About mixing both the digital and drawn mediums together - the stars are fine as they are, no glaring detail to make them seem different apart from being a bit light. The moon though is far too realistic, it doesn't really match the rest of the image. Maybe a filter or two might have given it a drawn/cartoonesque look and made it blend in more with the rest of the environment.
Color and Shading
Lot of nifty color and shading work here. The grass has different patches which could tell many things about the area, the different weeds/subspecies, its far more interesting than the same shade surrounding the tree. With the shading on the grass, you didn't use a straight up black pencil, but a darker shade of greenish blue. That’s a good method to follow, as shadows are never actually black in nature, they are a mix between the ambient sky and the surface they are landing on. So kudos for doing that.
The other light source besides the moon is the sparkler, where there could be an improvement or two. Since its yellow light, Espurr’s grey fur probably would be closer to a lightish yellow, especially with the white light mixed in. However the shading is still there, so its mainly the color itself that draws a few questions.
Theres a good variety of textures in this image, mainly due to the way you used color to vary them. Even though you only used black to draw the tree, it has a very rough and barky feel just by the line style and composition, even without color or additional shading to drive the effect home. Such shows a definite understanding of how the light and lines would work together to create a nice whole with minimal effort. The grass, by using again the line effect of colored pencils, gives this appearance of thick mats of grass covering the ground. While the fur on Espurr might have been more pronounced, the general ‘fuzziness’ of the medium does give it a fluffy texture.
I think as far as most things go, Espurr is able to be easily identified as itself. Theres a few minor bits of anatomy that possibly could have been shifted, mainly the top of the torso and head, where the widths seem a bit off when looking at them specifically, but they don’t take away from the general form. The addition of an emotional response to action, in comparison to the pokemon’s stereotypical death stare, is a welcome departure from the norm and gives us a better look into how Espurr feels while completing the action at hand.
For color and shading, both seem okay considering its a night scene and you were replicating the lack of light on Espurr via the use of a purple shade. I might have gone a tad lighter to better reflect the traditional grey,as with some of the focused lights nearby the darkness would be far less prominent. This would be around the face, and the top of the head where the moon’s whitish light would give a better representation of the color.
There’s nothing overly complex about the environment itself, just a nice simple hill with the lone dead tree on it. Its hard to tell if the tree is dead, or its cold enough that the leaves are gone. But since there’s no leaves around the base and its so grey, I’ll assume dead. Visual cues like a dead branch or two on the ground might have further cemented this assumption. The dragonfly at the lower end is cute, but are there glowing ones that come out at night? if yes, I want one. A lightning bug might have been a more accurate choice, but the general inclusion of a glowing insect is okay considering you have a sparkler to imitate its mate or something.
Since Espurr has a completely unique pose, facial expression, and environment, few bonus points for creativity. Also, I love the tree, its a very detailed and nice addition to the image.
A little more medium consistency/fusion of different art techniques like the moon will make everything mesh better. Otherwise, there's nothing horrible about the image, just some of the small stuff I already pointed out. As much as the lined paper could detract from the image, its not a big deal, so I ignored really pointing it out.
I think a few improvements would need to be made before it could pass for a medium.
