I love this!! I saw you're already fixing the issue of not being able to tell which tab is open (making it lighter would help more than making the others darker, though, since it's already pretty dark), so my only thing to add is that the first few tabs (the left 1/5 or so of the toolbar) don't have any stars - it's just black space and the stars only appear to the right of it, so it's distracting to me. Love the look overall!!
