yep, I've been rather inspired by Daelin's map too... but sticking to fantasy for now
It looks good (gotta zoom in though to enjoy the details) ... of critizisms I have the following: I think its a bit nebula heavy - I would concentrate (zoom) on a single circle or two, leaving the middle out - and I think you should add some parts of black space to the map - afterall, thats what one expects of space... deep black... neverending... darkness... sucking you in.....
looking forward to seing more
