I guess I like the colours. There hasn't been much changed to the classic template as far as I can see. The font is a better choice, and the colours are more pleasent.
Top right in FF 1.0 I noticed the sky blue bar at the bottom of the header is placed in the top right corner abo0ve the links - it doesn't look good as it partly covers the Links heading. Try and make it more level or remove that top right bar completely.
The first post seems fine, but after that, and again in FF 1.0 the content is too far to the left of my screen, with the text pretty much on the edge of the screen. You may want to shift it to the right.
Do you have a lot of content? If not, it might be worth you upgrading to 1.5 - it offers many more useful options, and better support for designing themes. If possible, I'd recommend the upgrade.
