I say you should...?

Depends on whether or not he actually gave some credit, dude. Also just depends on the whole situation in general. Hmm.

Did he claimed that work as his own?

im kinda curious now honestly
though if they said it was entirely theirs.. well that'd be a bit much

It looks like he is claiming it to me. No mention of who drew it.
Only that it was his first time drawing. lol

egh at the idea of this, but i wouldnt really know how to feel beyond a little insulted
in a way you be like 'oh hey someone liked it enough to color it' but at the same time..., i shouldnt try to think while tired xD
