Your color scheme is interesting. You have a classic black and white going, which is always a great jumping point for forums. I'm a little less sure about your complimentary colors. There seem to be a lot going on; I've seen red (2 shades), orange, yellow, green, blue, going on in different areas with your member colors. I would make your general text/link colors two of your member colors, and make the other two different to minimize the rainbow feel. Also, your banner/menu are different colors entirely, which clashes. I would also suggest changing the grey in the three right columns to black.
Graphics and images:
I really like your custom images. It shows that you spent a good amount of effort creating them for your forum.
Forum topic/theme and board content:
You appear to be quite skilled with graphics, so the theme seems to fit. I am curious though as to why you only offer various resources/ help to photoshop and gimp users. I would make sure that you are at least on the lookout for others proficient in other apps like PSP.
Coding and odds 'n' ends:
I would like to see your Quick links centered to match up with the rest of your forum. Also, I would suggest narrowing your forum to match the width of your menu bar or banner image.
Overall, very good start. Your layout is very attractive, and the only major suggestion I have is to expand your offerings a bit.
