There’s always room above the head in the pic.
Make two rows of stars: *******That'll keep them at a size you can count, and will work for 8*, 9*, right through to 10*Alternately, just 7*
The problem of squeezing 7 stars in one line will be when 8 stars are introduced. The stars would be too small then to squeeze in.
This is what I think the stars will look like, but I'm picturing the border being purple.
