If I'm not wrong, most of those sprites were made by Lucas Melo.
Your animations skills are getting quite impressive. You definitely have talent and your shading is also fine. You will improve with each new work, I wouldn't worry about it at all. I sometimes tried to teach people how to shade and so on and it turned out the best way is to simply wait, everyone finally understands shading, colors and everything much better over time, just like you do with animations, which get more realistic with every post. Good work!
Thank you, it's great knowing some people enjoy my work and support me, you got very impressive spriting style too.
I'll be improving what i have and try to bring more contente to this fórum.
