aaaw, another kindred starving artist. XD
What is most important to improving your own work is not condensing your subject matter to what others want to see, but improving on your own faults as you see them. The number of comments is inconsequential to the calibur of the work itself. If you can mistify only one person, then you should be satisfied, and ready to move on to the next piece, which will be better because you say it is.
That's enough preaching, though. I like that you're including some original characters, as well as some forum icons. Also, for your first foot tickle, its an inventive position.
