I'd say do it. You're loose nothing in any case but surely will gain experience. Just don't count on that as a legit source of income, as I see it - artist got to have huge metrics to make substantial sums of money out of it. But hey, some spare change can't hurt, right?)

Draw my fatsona and I'll pay you in exposure!
But in all seriousness, I think you should do it. I can't advise you on the financial side, but I do think there are enough people who may be interested in getting some art from you.
