Things I don't like:
1> The top bar no longer fits in 1024x768 even at my smallest text setting, which I can't use and still see. Any setting larger than "Medium" is just a mess, but that is a common thing in most sites unfortunately.

2> The fact that new artists and visitors won't be able to see my artwork as it was designed to fit in with the black background, or get so much of a headache that they will not want to even bother, without knowing that they can change it. Remember, that message at the top I'm sure will not be there forever, but the changes will. Even with the message, there are people who don't know they can change it and also it can't be changed without having to fill out your whole info.

3> The loss of the margins and the fact that the pages with their table boxes looked jammed into the page in order to fit the side text bar.

4> Automatic drop downs, so that if you hit the mouse wheel you are thrown all over the place, places you may not want to go.

On the other hand, I do like the logo and I don't mind the brown sidebars/drop downs and while not a big thing, I do like the My Gallery in the dropdown. Now that the colors can be changed for the main window, it works for me, but as I said in #2, the new default design is going to scare people away...
