It's a great combination that looks simple and uncluttered. That's my goal, I want something that has the important stuff to hand with ability to reach the stuff rarely used. Most themes try to add too much jazz to make it look smart and stand out more, but personally I prefer the idea that less is more, if done right
You may not be a graphic designer, but you've done an amazing job with your selection of colours and shapes for this theme! Hope you can finish it soon
