I gave the ux-simply.com site a look. Seems you’re a very talented designer.
What was missing for me (thinking as a hiring manager): I couldn’t see anything in your work that showed me what you would do for me. You’re making me look through your background, experience, and talents, and making me do all the work to see how you’re useful.
If you think about this, this goes against the process you lay out in your first portfolio exhibit. In that exhibit, You talk about doing research and figuring out key measures for success. Where have you demonstrated that in your portfolio, with relation to any job you might be applying for?
I recommend you look into an performance-based hiring technique, like the one that Lou Adler describes in the Essential Guide for Hiring and Getting Hired. In that, you’ll see that a generic résumé and portfolio won’t help you land jobs, which sounds like it matches up with the experience you’re currently having.
Hope that helps,
