i would like to be the first person to reply with "LENS FLAER!!!11!!1!"
now on to the real suggestions...
maybe a few more brighter stars or less of the dark ones, maybe also a few smaller planets around the sun with moons, and perhaps a nebula/gas cloud, maybe also a halo or glow around the sun, right now it kinda just looks like a yellow blob, and also maybe an ozone layer for that planet, also a bit of space debris might help liven it up.
also, how did you make that starfield? it kinda looks like you've used a noise filter, a good way to create them is to start off with a white background and go over it in black with a large airbrush tool...
apart from that it's really nice
