Appearance (First Impressions): 15/20 I like your dark theme, but you have very few colors on your forum. All that I really see is grey, black, white and blue. If you incorporate more colors, I think it would look a lot better. I am giving you bonus points because your banner looks so good. I think that if you get rid of some of the default icons (I don't know if you can on your host) it will look like you are really good with graphics. That would make the site look a lot better.
Layout: 14/20 Your layout is ok, but there are too many forums on the index page. I think you should combine some of the "Graphix Requests" forums, and make some other boards sub-boards, so thatt your layout is smaller. I also think that a lot of this is because of the "Graphix Navigation", which I think should be gotten rid of, at least for guests, who won't have any new posts since their last vist. Not to mention that many of those it makes you log in for.
Number Of Members: 9/10 You are getting more than a member a day, which is great especially for a graphics forum.
Number Of Posts (Spam or Otherwise): 7/10 When I look at the forum total, I think "Wow! Over 100 posts per day!" but in fact about 1/6 of those are in forum games, which doesn't look so good. If you want to have a lot of forum games, I would suggest hiding it as a sub-board of a general discussion forum, so it look like all those posts are in general discussion. I would suggest trying to get your members to post a lot elsewhere either way.
Moderation: 10/10 Though I cannot log in to check how many moderators you have, it looks like you are online everyday, so moderation shouldn't be much of a problem. I see graphics mods, but I am unsure if they are regular moderators too.
Activity: 19/20 I think you are doing very well activity-wise. Most of the forums have been posted in recently, and the ones that haven't don't really need to be posted in a lot.
Spelling and Grammar 9/10 From what I can tell, your spelling and grammar is good, but there are some mistakes here and there. It isn't a big issue though.
Suggestions See Layout and Appearance. I think that Is where I made all of my suggestions.
Overall Mark (Out Of 100): 83/100 You are doing very well, and I see a good amount of potential in your forum.
