This one didn't turn out quite like I wanted. I wanted to add some illumination to the emeralds, but it ended up making the character look washed out. I guess this was just practice on shading and highlighting the characters more than anything else...
Oh well, I might go back and work on those emeralds later.
Quite a bit of action going on here, but it turned out really well. I think the scene would play out like this:
Amy: Look! This is so cute, right?
Sonia: Oh, ! could totally pull off that look!
Marine: Pillow fight!!
Rouge: Hey! Watch the tail, squirt!
Tails: What are we doing here again?
Manic: Heh heh...this is so awesome!
Sonic: ...if we get caught, you're toast, bro!
Blaze: I thought I heard something outside
Something tells me Manic and Sonic are about to get busted...
In case you haven't noticed, I'm really trying to incorporate the highlighting style from the official artwork. I think it's looking better and better, at least in the face. I need to work on body shading and highlighting too...
