Ohh my, I'm sorry to hear that, is everything okay? You shouldn't worry about finishing it at this time, just prep for the next contest or so if need be! Don't push yourself!
Oh, I'm just fine, but thanks for your concern. I simply took on more work than I should have, but it's okay now. I can finish this thing before starting the next ones (as long as my studies give me time to work on art in the first place). It's something I don't want to leave unfinished.
