Three Squared Designs

There's a lot of good in this design, such as the presentation and choice of color. Against the dark background, it's easy for colors such as greens to be a bit overwhelming. The tone of green that you've chosen is a bit muted, but against a dark background it definitely pops out a little more without being straining on the eye.

The organization of this page is good. Clean, concise, and it definitely is visually appealing. The general use of typography to call attention to the various elements on the page is very effective, although the white text used for descriptions and things of the like may be a bit too small. Sitting at typical distance from my monitor, I'm able to read the text, but it involves more visual processing than I think is necessary. Kicking up the font size just a little bit could be a good way to go.

I'm a fan of the texture separator under the top navigation, but it's disappointing that it isn't used again throughout the rest of the design. It seems inconsistent to use it once despite there being a lack of likewise elements on the page. Similarly, the image you've chosen for the header could use a bit of color adjustment to make it pop a little more on the page. With that, the text on the image would probably be better white. As it is currently, the green text doesn't really work with the red tones present behind it.

Another thing I really enjoy is the footer. Very clean, professional, and the headings for each section stand out in an appealing way.

This is definitely a great design, and with a little refinement it would become even better.
