Hey, awesome stuff you're producing out of simple spheres!
(I couldn't help notice a few familiar "resources" (altered & modified enough) from a number of freewares & softwares which, btw, doesn't take anything away from YOUR hardwork!)

Besides, who wouldn't gasp outloud at such a frog face knowing whom it may be tagged for.
From an artist (not to sound edgy or braggy) to another... some great work.
