Very nice to see more from you, homeslice. I hope you win.
To critique, the lightning was very basic looking... you didn't really involve a lot of creativity with making the lightning that was in sasuke's hand. But hey, I guess it got the job done. The lightning sparks were good, and the crumbling effect of the pikachu's lightning was also nice, as well as the disintegrating look of the rocks underneath pikachu.
I must say it's an original idea to put those two characters together... lol quite an unusual match.
Now, you've got good skills so far, but you still have things to practice on!
1. Line Art - Yours still seems a little crooked and rugged. Are you using the pencil tool from flash? Probably shouldn't for this stuff, it doesn't help you.
2. Lighting and Shading - There are two significant light sources on the left and right side of the picture, but the shadows and light reflections on everything tell a different story. Still, you showed effort in shading sasuke's arm and stuff, so I'll give you that. there are still a lot of shadows and highlighting missing.
that's all for now, thanks for the artwork.
