Both designs are nice. The first one might not work for greater consumption on DW since it's not very flexible (fixed width, width of header image, width of sidebar). The second one works better since it is fluid width and it can work with an existing layout base (Transmogrified and Bases). The only problem I see with it is customizing the blue color to something else. Images are used to create that effect, and I'm not good with images.

Here is the license for that layout: http://templates.arcsin.se/license/

I'll keep it in mind when choosing what to work on next.
