I like the second one the best. You can see the details of the first guy's hair better, which happens to be my favorite part of the coloring. My only crit is that Jiraiya's hair is too dark in some places.
I loved the second better. You have improved alot KS, your coloring has improved greatly. The soft cell shading is excellent, and it is overall a very nice composition. And i like the shading done on Jiraiyas hair, keep up the good work.
