Its pretty nice, but i think some of the render doesn't look that good in that it seems too apart from the central focus - i think how the bottom right part of the render being joined via brushing looks good and you should have done with with each strand of the render. Some of the render also seems like you have blurred it to merge with the background which imo doesn't look as good as if it were in space and your render/brushing was just floating. I really like the central brushing its pretty awesome, GJ
