Yay! Thanks for the feature... I can't remember if I've featured any of yours yet, I'm working my way through my faves in order without asking permission first...whoopsies
i'm just old fashioned and wanted to be sure it was okay with everyone - so much art goes astray - didn't want anyone to be upset 
and thanks 
i'd appreciate a feature by you too whenever you get to it 
ah...well frog references are allowed...you could try quick sketching a frog at home and then add spikes and such at school...most of my frogs are done with references although about half of the thumbsshare frogs were just from my head
