yay! Time for C&C! *random clapping people* ^^ Aaannnnyyyways. I like them. Some a re good, some are bad. Some are like OMG IT BURNS! TAKE IT AWAY AGH!(okay, not really. I'm hyper off coke) Okay, the first group looks like regular pixel spriting. The main bodies are excellent, not off balance or anything. The Outlining is a little shaking though and needs more colors and the shading could be blended a bit better. Iggly is a little too dark but very nice. mew is the best of the three. It would be near perfect if the outline+shading was fixed. Latios is good but WAY to shiny plus the outline is shading again.
The next guy is sorta pixel art, sorta not. Its very nice and I like it but the outline shouldn't be so thick. It should be like 1-2 pixels thick. The shading is excellent, but it just seems a bit squished. Very cute ^^
Eeve has some similiar problems to the first three. The outline is kinda shaky but the shading is good except for the head and tail. the headfluff coul use some shading. The eyes are cute but... they just seem flat. Good job though.
Umbreon is excellent in some ways, bad in others. You did the same outline problem as the dog guy earlier. the rings' shading are all 3-d, very nice but the body shading is a little weird.. the forehead ring doesn't follow the forehead shape and the hind legs look weird. Pretty cool though.
The last two have similiar problems. They look a little outta porportion and the outlines+shading need fixing
Anywyas, not to bad for a beginner. Keep drawing ^^
