Looks ok to me. It has a real film image quality about it, nice work.
Your shot is much better of course but here is a film shot I took some 25yrs ago through an 8" F7 Newt on a Samson mount with a crappy AstroOptical delrin drive gear wheel drive, to compare, scanned straight from an old print unfortunately.
