Kyren has dark hair right? It's brown if I remember correctly.
I have the photo for Derek assuming you're talking about the b&w one. how would you like his expression??
I ain't drawing Gary though. I have a problem with that kind of hair so I'm not drawing him until I get around to doing a proper Gary/william couple art. I think I have a harpy avi of yours saved... >.<

But I'll draw you a few things.
