Young artist - how to sell work/get noticed

Not sure if this is the best place for this but it's a little confusing. I started taking commissions nearly two years ago when I was 16, doing horse portraits in pencil. I'm now drawing various animals and it's going fairly well, and making a good bit of money considering I'm only a student I guess! I'd love to sell prints though at some point and do want to get away from just the pet portraits (which I find a little boring & repetative) and do mostly equine art. I don't quite know where to start though, at this stage I have no drawings I would want to make into prints or I feel are good enough - I'm working on this though and have been out with the camera and am working on a set of 4 A3 drawings that I hope would make a lovely set when presented well. Where do I start though on finding places to display my work & getting prints made? (I am in Cheshire if this could help...) I would love to get some art in an exhibition at some point. I am also a member of the Society of Equine Artists although haven't really done anything with that since joining. Any tips would be much appreciated, and if anyone wants to have a nosy at some of my work & give an opinion ... www.ramelia-images.com Thanks, Rebekah
