Wow, expensive puzzle! But at least you learned something from it, I suppose... I'm sorry you could never complete it, though, that must've been disappointing.
I think these came out really well, too! I wouldn't have guessed they were done in mouse, for sure, though I wouldn't knock the pad, either. Different types of art, slightly different aspects of a skill, so I'd say keep at it! Who knows, you might achieve things with the pad that would've been unlikely with the mouse. :)
thank you very much.
