First off, puns are awesome. Pokemon based puns in artwork? Even better.
First off, use of colors that contrast is good, the tan allowing Surskit to stick out more and thus pop out. The colors are also indicative of a cool, dry location, which the image fits perfectly as well. For weight/balance, its a rather empty image overall. All the focus is being places on the pokemon, since there's little else for the eye to grab on to. Which can be good, and doesn’t necessarily hurt this image, but a few more details or small additions to break up say the darkness, like shadowy forms or pillars, etc could be good.
One little thing that I noticed when viewing up close is that pixels can be seen in certain spots, like an attempt was made to smooth out but it didn’t quite work. Especially noticeable around the hat strap, just be wary of that.
Surskit is just as it’s ranking states, simple. Everything looks correct for the most part. Shape is good, since its immediately recognizable as the pokemon. The pith helmet is a nice way to still show the Yellow spot on top of the head while being original. Color is good, shading works for the most part, although I’m having problems nailing down the lights location (see environment section). If I did have to find something wrong with the pokemon itself, I would nitpick that the legs could be a bit longer.
It a very basic environment, but quite fitting for the pun as I can assume you intended. The way the stone lines fade in and out on the floor are good, gives the appearance of dirt and sand covering them. For the walls, I would have possibly just made the creases lighter, as right now it seems odd that the blocks would be fused into one. More textures on the clocks would have been a nice touch too.
For lighting, I think overall its good, you added a few levels of shading and shadows, most notably the black abyss directly straight ahead. One thing that seems just a hair off is the fact that Surskit’s shadows are straight down, when the light seems to be coming more from where the viewer would be standing. Its a small detail, but one that should always be considered when shading an image like this.
1. Shading can always be improved based on the intended direction of light, especially shadows being cast straight down as opposed to at an angle.
2. Possibly adding more detail into the scene to add more for the viewer to see.
it works, and you did work. Have a Surskit as a reward.
