I like that size much better, but bring back the brightness of the shiny things! The only thing I'm thinking about now other than the loss of brightness is whether or not the big rock to the right is too distracting ... because I keep looking at it when I don't want to. So maybe try and put something over that? Or maybe blur it out a lot.
I'd try a couple different things, but the blurring idea sounds good because just putting another black piece over it would just make all of that a big black hole which would be meh.
