Don't worry - the quality of the drawing I produce tends to depend on how many drawings I've been doing. :) The more drawings, the crappier they get, and I end up doing sloppy stick figures.

(And I've got an iPad and a stylus for it--I haven't dared try the iPhone screen!)

The one I just sent you ... man, I got 3 words, none of which I was sure how to do, so I picked this one and have no idea if you'll get the concept I was doing. I hope so!
