Oh hey, a shiny Kricketot. Cool.
The colors in this are great. The blue in the background contrasts with Kricketot's orange colors nicely in an opposing color wheel usage. Good job! I also see some basic background here as well as clear edges and boundaries on the Pokemon and the trees in the background. You dont' seem to have any shading, however, and it seems that your drawings are a bit sketchy and unrefined. The background is simplistic, but this is a Simple Pokemon so that's okay.
Color choice is great, and like I said before, using blue next to orange demonstrates knowledge of the color wheel and an eye for contrast. Looks good, though I wish you'd put in some shading of some sort.
Near accurate--his nose is a dark orange and not black. The lines on his belly should also run straight down and not meet at the bottom as you have here.
1. Neater lines and edges. Clean up your art; it makes a world of difference.
2. Pokemon accuracy. Make sure you get it exact for maximum points!
3. Stagger your background; make some objects appear closer, others farther away to give your image some depth.
4. Give your Pokemon some shading. Finding a light source, highlighting, and shading give the picture a more lifelike feel and make it more interesting.
I give you the 25/100 you need for this Pokemon. The reason the score is low is because of the lack of neatness here, the simplistic background, and the lack of shading. Keep on practicing and you'll be able to catch higher leveled 'mons next time! But for now, Kricketot is caught.
