I love your work. You truly do have talent for sculpting, but I'm sure it's not the only thing you are good at.
The prancing horse is great, but my favorites are the figurines. The one with the kneeling girl hugging herself really get me, it's emotionally powerful. You really get a sense of loss, lonelyness and despair from it. The baby is sooo well done to but it's scary and creepy to me. Maybe it's the finish but for some reason it makes me think the baby was caught it a nuclear bomb and frozen in it's last scream...brrr gives me chills.
I'm an amateur artist but I don't think I've ever created anything so emotionally engaging. I don't think I could ever be a pro-artist since I go for long periods when I don't want to work on art at all. So I take it as it comes and if it's not going the way I want I can walk away from it for awhile. You can see my work at: www.paintingsilove.com/artist/shawnw
If you truly want to pursue a career in sculpting but college is out of the question financially I would encourage you to just keep working on your art. You will still develop as an artist just by continuing to work. If you truly want to go to art school then make a plan and figure out how to pay for it. There is always a way if you are willing to work hard at it. I think your talent is worth developing any way you can.
I'd also say look for local artists groups, they will support and encourage you, mentor you, and help you sell your work.
Good luck with your art where ever it leads you.
