Fyron:
Looks good.
Any chance of adding a few huge red giant stars?
Also, I guess the red star you have in the screenshot is a red dwarf? if so, it could be a bit smaller, some of those stars are actually not much larger than the planet jupiter, (not all would be that small though):

Another nice site that compares planet and star sizes (to put things into perspective):
