I think a revamp is completely called for. To be honest - I personally think the site is too cluttered with ads and some miscellaneous images at the top. I would remove a good portion of all the 'fluff stuff' - for instance I'd keep the forum home a bit more simple like so:
I'm not sure I understand what you're trying to accomplish with the CMS. I would definitely advise an overhaul of it's styling so that your article posts are presented in a more professional manner. Also - the style itself is really giving me more of a militaristic feel than an arts and animations feel.
On a more positive note - I see you have quite a bit of content, with several users online. At this very moment you have 30 members and close to 100 guests browsing your forum, which is AWESOME imo. You might want to poll your active userbase to see what type of upgrade/overhaul they'd like to see you make, especially as far as style is concerned. You want to give them what they want you know what I mean.
You've got your work cut out for you. But if you keep at it - I'm sure you'll have the forum you want and that your community deserves.
Good luck!
