Perhaps you could say exactly what you don't like about it, I don't really want to replace it with someone else's work but if there is something in particular that you don't like let me know.
There is no banner that will be liked by everyone, people take to different motifs, it is a simple fact. That's why there are multiple skins, to allow members to alter the site to their liking to the greatest possible extent. There are some who take a liking to the pure black template, while some keep asking for a light one (for example). Some like darker banners, some like lighter banners, some like many colors, some like simplicity, some like a metallic look, some like a more organic look, some like a look that is more in motion (creative use of blurs and whatnot), and some simply like nice text.
In making the banners, both the one on the main site as well as the one on the undocked forums, I made an attempt to incorporate older motifs into the new look. So we don't seem like a new site all of a sudden. Certain elements such as the blue star, the 'Griever' lion emblem, warped space, and that blue crescent in the CurvedSpace logo all are symbolic of our site in some way (the blue star and the crescent going back more than three years). Since it is CurvedSpace I made it revolve around the warped space look, but since it is also SeeD I added the Ragnarok to it which is not out of place in a space motif. Basically there are some nitpicky things that need to be there and can only really be designed by someone who knew the
old site and how it progressed.
But as I said, if you have suggestions just send them to me. And yes, I use Photoshop, but I also created that banner (if you're talking about the one on the main site) at 2:30 in the morning.
