Personally, I dont like the mix of serif and sans-serif fonts on the page. I would just stick to sans-serif. Apart from that, I like the clean crisp look.
A very important design rule never use more than 2 diferent fonts, specially if you are going for a clean look... you have 3 (yes, the logo counts too) and both, serif and sand serif (wich looks very bad , because you use basically all typography) I would suggest you go for a san serif, but maybe courier new could look good, I don't know.
Another thing, the titles get a little lost, since they are lighter than the body text.
There is alot you can do with a good css file, play more and have fun while doing it!!, you have a great start. You just need a little more order and structure.
If that sounded hard, wasn't my intention, just giving my opinion. and sorryfor the typos. =)
-----------/ this isn't a fucking soap opera, (liquidred)
Your "tutorials" "links" and "gallery" pages have some alignment poblems (I dont believe the text is supposed to be going through the divider bar in your main text window) I'm running it at 1600x1200 if that helps. Other than that, it's not bad. Very minimalistic, but pretty clean. Might want to take a few suggests and check out some other fonts too :)
I think a version 4.1 will be in the pipeline. I'm definately going to tweak this design, I like it but its not finished, for sure.
With regards to font styles I think it works ok, I might change the 80four image in the top left though. _________________________________ http://www.80four.co.uk
You posted this on theroot42 forum's didn't you? Looks like you've cleaned up the alignment issues, and made a couple changes. Overrall it's better than the last time I saw it. Nice work.
