Work on the copy on your second section. Change the phrasing. Make it more conversational. Some of it is a little wordy and stiff, sometimes it's even confusing. For instance: consider changing "We only add parts to a design that works" to "We only add elements to a design if they serve a purpose." Include some catchy phrasing like "Less is more" ,"We focus on functionality.", "Functionality is its own aesthetic." By design is science I assume you are referring to occam's razor. You might want to make that connection somehow in your copy. Also, the last phrase needs to be "We make sure your design appeals to others as well as you DO" The other bullets need similar re-working done.
If less is more for you, considering taking off the opacity elements in your graphic design section and, even moreso, in your photography section. It detracts from the user experience. People want to scan your photos and get a general idea of your style and ability. The eye moves much faster than the hand. This discrepancy proves for a clumsy feel, which will ultimately get in the way of the mental process of the person evaluating your work. You don't want this dissonance in the sales process.
Similarly the module that you've used to present your web design portfolio is super nifty. I love that thing too, but you haven't integrated it well in with the rest of the site. It's hiding your content from the user. That's bad design. You'd be much better off with a 3x4 grid of thumbnails with some simple size and padding rollover transitions. That way I can see your designs clearly without needing to cock my head to the side and without requiring user-input
Contact us: the envelope below the text is hard on the eyes. It makes reading difficult and most won't even recognize it as an envelope. Again, simplicity with the design. Configure the elements in such a way that they create a cohesive experience while accenuating content.
Do a line break with "Like our work." I would experiment with redueced font size and slight color changes on that text to call it out.
Another line break
"Contact us for a free quote"
Another line break
Your envelope exactly where it is
Last, but not least, increase the height of the "your inquiry" form so that feels more like an object. It's jumbled together with the social networking and copy-write information. Increase space between the submit button and the 3 social networking buttons.
Hope this helps!
