well first of all i want to say that the artists gallery is very well done and layed out, so fair play on that. I do think it needs some work to be recognised more on the homepage. maybe something like under fanart, you can see the last picture posted in, and people will automaticly know that there is a fan-art section(or artists forum) in eoff.
Other ideas could be maybe just the small things, have a better profile for members using the art gallery, in which under theyre name when you click onto theirs would be 'submitted fan art' or whatever, so people could access and recognise your pieces from there.
