So I was looking for a new theme today and stumbled across your thread. I went to the market and found the Azure theme and installed it. Very nice and I think that I will be using it for a bit. One thing that I can mention though. Your other themes in your profile are almost all outdated (from a few months ago), so not sure if you need to update them because of the recent Theme Engine commits, but I suspect that you might. I haven't installed the others, mainly because the latest version on the store is around July area for multiple ones.
Just an fyi and very nice work so far. I do hope that you will continue to work on these and progress yourself a bit further in the theming world. You have very good potential for your first effort.
