You should have gotten the gist by now... your odds of getting into this business are not good. You’ll have to be phenomenally talented and an excellent businessman (or woman) to market yourself and your skills and pull in enough dough to support yourself. Your bra can only do so much.
Your chances of finding some work or selling some of your drawings are good, however. It will be a great feeling to see your work in print, but if it doesn't happen often enough to pay the bills, you may have to throw in the pencil and call it a day.
