Well woosterbert, now you have been talked about
The image on your main page is really interesting. However, I have to say for a graphics site, I would not have gone beyond the first page to ever find out if there was anything else interesting inside it. You did say you are new at this so you know you have a lot to learn. That is good. It is an attitude that should allow you to dress up your site and make it successful.
First, the text on the first page is all in such a light color on a white background that I couldn't even begin to read it without highlighting it to give it some contrast. You definitely need to change that.
Also, because it is a graphics site, I would want to see some nice graphics involved in the menus and incorporated into and around your text. You need something that is at least somewhat original in menus and page layouts. There are some nice CSS menuing systems available that with a little creative use of graphics as backgrounds, could make a nice menu for your site. This would allow you a very SEO friendly menu system and you don't have to write much or any code. You do need to be very good with HTML and CSS.
You have some nice images and designs inside the site but you need to work on the overall page layout and design to get people past the main page.
Good Luck and have fun.
