the new banner. It's so cute and very fitting for cuccoscratch.

I know this is just a concept, so a lot of images and other finishing touches are not yet present, but I think it would be cool if the backgrounds (the turquoise and/or the light purple parts) had more to them. Like maybe another art background (such as the background on the current cuccoscratch.com), but kind of faded so the text would still be readable over it. But maybe I'm thinking too far ahead on that, so my apologies if I am!
I agree with Cass that maybe the main part of the page shouldn't necessarily be all links to News/Announcements. If those links could incorporate other boards, like Gamer's Basement, Reviews, Art, etc., that would be cool. I know this place focuses more on Art, but I think it's important to also show it's not an Art-only forum. This place also has an attraction for those interested in gaming, or other people from NSider. It would be nice to have the main page to try and draw all those kind of users.
I like the intro on the current page of cuccoscratch.com, where it says why cuccoscratch was created and such. If that somehow could be saved and placed somewhere in the new format, I think that would be cool. It will also tell users that more than just artists are welcome to join here.
I would also switch the order of the "Users Online", "Welcome, <username>", "Navigate" sections on the left side of the page. The "Users Online" area might get long, especially since we are constantly getting new members, so I think it would be better if you had the "Welcome, <username>" options always easily accessible without having to scroll down in the case of there being a lot of users signed on. I think ordering these sections as "Welcome, <username>", "Navigate", and then "Users Online" might be better. This way the only reason why someone would have to scroll down is just to see the users that are online, and not something they want to access, like their inbox or the logout option. I also think it's more conventional to have the "Welcome" part at the top too.
Well I guess those are my opinions.

Hopefully they are okay and kind of helpful.
