Jakiller you are off to a good start!

Upon first glance of this web page I get the feeling that it is meant as a portfolio site for someone who is very graphic, as a designer or photographer.

I shall start at the top of the page.

Navigation:
The logo having the black arrow pointing at it is great to show the view who this web site is for. Unfortunately it is too small to convey a real feeling of the company name. With a name like Ambitious, the logo should show that it is ambitious.

The navigation bar itself is very nice and stylish, great job with the dark colours, and an amazing way to show which page you are on. You use yellow and blue throughout the design. I suggest using the yellow and blue as part of your active and hover states for the navigation.

Sub Nav:
Great Idea to give a legend of the work that is being shown, but I think it is unnecessary. You could use a pixel font on that little banner you are using to explain what the piece is.

Content:
The site is very well laid out in a grid and is quite visible. I would suggest making the boxes slightly smaller so that there can be some spacing in between each of the pieces. As it is right now, it looks like you are showcasing a collage of work, instead of individual links you could click on.

I would like to see a rollover effect applied to the images, something that tells you the name and something about that piece before you click on it.

Footer:
Interesting use of the iPhone. I would put the iPhone in the upright position and add en your email and web site addresses in addition to your phone number, since the iPhone can do all of those in one device.

Overall:
Nice clean dark design, that works. Working on spacing so that everything has a little more room to breath.
