hmm...tough spot you got thar D:> I hate artblock, so I'll try to help the best I can. First, listen to music that inspires you, my music is either Disney or if I want Instrumentals, David Arkenstone, watch movies you love, look at art you love (mind you I'm not saying to steal art) and dream. Dreams, or even reminisces of dreams can seriously help since that is when your mind is most active in imagination. Read BOOKS! I have one that I bet you can find somewhere on the internet, the Imagineering Workout which can seriously get your mind flowing. I hope I helped ^^
thank you
