A duo portrait I did of Fiona Fox [from the Sonic Archie comic books] & Wave the Swallow [from Sonic Riders]

I'm not too sure about the dimensions upon my secondary review of this :-.
Looking for any constructive comments which I can put to future submissions, as I've noticed on earlier pictures that I've still not got scale down to a T yet . Feel free to leave me any.

Fiona belongs to (c) SEGA/Archie
