That's a really nice piece. I don't like complaining about hand drawn line-art, because it just gives it that feel that you worked really hard and put a lot of thought into it. Though one criticism I can give you is the shading(specifically on Blaziken). The light source looks like it's all over the place, and the mouth shading doesn't look too good(for lack of a better word). But overall, it's a good pose that Blaziken is in, and those are some pretty cool eyes on that Pokemon.
Your friend looks good, though the eyes could be a little more together? Unless your friend has really separated eyes or something, but you know. That's just my opinion on how to draw a person.
Keep up the good work, man.
