Good job! Seems like you've done a lot of work in this piece. :) I love the comics style and the overall attention to detail, it really is great! Some aspects I wanted to point out though, I think you can improve a bit more on the your textures, especially the suit of both the characters; moreover, exaggerating the poses and more specifically the facial expressions would really make this tyoe of piece stand out. :) Nevertheless, you really did a great job on this!

This is really great! The mixture of realism and comic-ky effect that the illustration seems to communicate is perfect. Good job my friend! :)
