It's wonderful to see all the support you're getting. I hope you don't mind if I post again on your thread... I keep thinking back to when I was 16 and reminiscing about the way life was as an artist before college and kids and a mortgage and so on. It seems true to me that life just keeps getting more complicated as we get older, though perhaps more meaningful too. To me, the beauty of being a young artist, putting lovely work into the world like you are, seems to be its simplicity. I assume you make quality art because you love to do so, not because you have to pay all the bills. (That's the sense I get from your description of your portfolio site, at least.) The opportunity you have to create from the essence of who you are before trying to create to please others, or fit a specific market, or target certain clients seems like a treasure chest of jewels to me. If you're doing what you love at a high caliber, opportunities will surely knock, and you can answer them as you choose based more on heart and less on money.
Sincerely wishing you all the best... :)
