forum banner design

I am looking for a banner for my forums, [login to view URL] that is similar to the banner I have created, (but obviously better) except wider. Currently mine is set at 691 pixels, I would prefer one at 800 pixels width. Here is a brief description of what I want: 800 pixel width, 130 pixel height, similar to the current one, except more digital apperance, perhaps with a mascot designed to go with the website theme. Definately more cartoonish. I have uploaded the current banner also, although I would prefer one created from scratch rather than built off of this one. (I wont accept if you don't have a functioning portfolio either.)
