First thing I would do is remove the shadow below your text.. it makes it look like it's floating (which is odd) a closer drop shadow would be nicer
I think maybe changing the font of your header and increasing its size would make it look better. Looks kind of fuzzy right now. The rest of the site looks great. You might want to include "mylastshot.com" in your title tag.
I agree...Change the font of your header. Everything else looks sharp, so you would want to contribute a great header to blend in with the look of the rest of the site.
I don't see any drawbacks of this site. It looks really nice. Maybe the header section could be a little bit lighter.
Your silver-blue colorscheme is great, I like the idea of "Latest Active Forum Threads". But the homeI forums discussionI........ horizontal bar isn't impressive, maybe use buttons instead of simple white text. The animated smilies in your shoutbox, disturb me while reading the text, remove them. the rest is great. Good luck with your project
