It's okay. To be honest I'm the same way. I make a really cool piece, and I love it, but then it loses a contest and I don't really care for it as much anymore. Hence why I don't really enter any art competitions anywhere except the pixel art challenges here. You had the courage to put your piece to the test, and that in itself is great :3
Hey, just thought I'd tell ya that I really thought your Wargle picture was good. Really the biggest reason you didn't make it into the top 5 was that there were simply a lot more than 5 great pictures :3
I think Wargle's one of the cooler Gen 5 Pokes, too.
