I've been thinking a bit further on your work guys. There must be some local art shops near you. If you frame some of them up and contact the owners of the shops, they might even sell them for you
To be certain they might be interested have a look around the shop first to see if they sell anything like your work first and check out the prices. Bear in mind if you approach the owner that they shop might only have low margins, so don't expect a high price for your work. And don't just turn up with your work! Phone them up to make an appointment first.
You never know what they will say untill you try them though
In the end it might only be small sales, but as many of you appear to be at college it could help with fees, materials etc.
It should impress your tutors too, if you shown that you can sell your work
