I really really wish that I could draw, but even though i can't I still get inspired to make music...I usually look to my surroundings for inspiration, almost like giving a voice to my environment through music. idk, it might work differently than that in your case, since you draw stuff, but I thought I'd give my opinion anyway. I've been though those inspiration ruts too, they suck because it makes you feel like you can't communicate accurately, (at least in my case). Anyway, I hope you get out of this rut you're in, but I'm sure you will!!!

This may have been just the help I was needing. THANX!
