Deviantart is full of shit, sure, but I feel bad picking on the little guys. I like to keep several tabs of Rob Liefield drawings open when I draw. It's simultaneously encouraging and depressing, and nothing gets the creative juices flowing like depression!
By the way, have you checked out the Tumblr blog, "what-the-fuck-deviantart"? It's full of horrible art that makes you feel like Piccaso in comparison. (i found plenty of sparkle dogs and bad MLP ocs too. )
I see stuff, I don't understand why people post it. If that is the best you can do, you seriously should take lessons. I don't know how others see my art (like I actually bother uploading much stuff), but if it fails I delete it. Nobody is interested in seeing your fails.
