Thanks everyone,
Yes
http://www.wildlifeart-online.com http://www.wildlifeart-online.co.uk and
http://www.onlineartdemos.co.uk
are exact duplicates as I mentioned above, my host just point each domain to the same files. Basically I was mistaken into thinking it was a good idea to use up the spare domain names I had. Damn.
So do you think I am already being penalized or am I likely to drop off the search engines when / if it happens?
So, should I just remove the two wildlifeart-online.com and co.uk sites for now? and stick with the original and better ranking onlineartdemos.co.uk and then write different content for the other two?
I Really appreciate the input, I hope to eventually become a full time wildlife artist so perhaps I should stop doing things myself as suggested and concentrate on the paintings instead?

would I be talking big bucks to get this sorted out? I don't think I am up to optimizing it myself much more I think I have just about gone as far as I can, I've tried my best and think the site is pretty decent for an artist ha..... but perhaps I need someone who specializes in this?
