Im not a huge fan on this forum skin to be entirely honest with you, which is odd as 99% of the time your work is outstanding. In my opinion the things that I dont like are:
1 - The navigation is too dark and blends in with the background to much.
2 - The purple background used behind the content is also too dark, I find it difficult to read the text easily.
3 - The colour of the text used for status, forum, last post etc. is not nice at all.
4 - The main background colour itself is very dark, which is nice in some cases, I just dont think it fits here.
Best of luck with it all..
