Damn, the second shot is just perfect! The lighting is amazing! This image is a perfect example of what kind of results one can get with good lighting, instant upvote. :)

I like your approach to improving your skills. I hope it is indeed helpful to you. I have trouble even posting one picture every day, haha. But that's mostly because I just don't have the time to. I can spend anywhere from 3-6 hours taking and editing just one photograph, it can get quite tiresome if I do it daily along with all the other stuff I have going on in life.

Anyways, well done! Keep on posting, you have unique and interesting approach on this "one photo per day" thing. :D
