You've got some good work there! (Sorry, I'm hopeless at giving compliments. It's all..."That's...really...good...do more." So
original.) Anyway.
If somebody commissions you to do their character, incidentally, how can that be an infringement of copyright? That's what I thought commissioning was all about...you could lose yourself some serious cash there, y'know!
'Google made me do it' - Search engines can be funny little things, can't they? I like the way you've coloured this. God, my scanner mangles anything with a drop of ink on it (praise be to my Wacom and Photoshop, therefore).
Ivy is damn pretty. I'm liking the poses on Rek and Lu, though, and I'd love to see how that would turn out if you took it further.
Overall, really pleasing work.
I'm jealous, seriously.
