"...About the size, you think it will be too high?..."
I don't think it's too high - if you like it there, leave it there.
Question... Will any of the buttons on the sphere be the same (link tothe same tihngs) as the ones along the bottom?
1- Change the font used in the line "2004 S.o.S. All Rights Reserved. I would use something smaller - and without a style (not bold or anything) - hard to explain as I don't have a particular font in mind - just something else.
That's just my opinion of course - I wouldn't say it's "bad" as is.
2- Make the logo (the guy) smaller so he fits above the black line he cutrrently sits on.
3- Once the guy is smaller, I would bring your navigation (buttons from bottom) up to the top, just above the darker grey "body" section you have.
Overall it looks great - the sphere and the logo are very nice
It looks like you may have had some suggestions at DeviantArt as well - I just can't read em - haha.
Not a bad start by all means, i would change the font definately. The font is a bit spaced out and doesnt really look like it should be there. Some suggestions on font choice - Steelfish should work very narrow, and very modern looking. The man is to big in my opinion i agree, go for a horrizontal nav, you could even sit this under the guy, as an overlap.. you will have to play around with this. Try and key that bar into the circular shape in the top left, which looks very smooth.
