Don't put the basketball right in the center of the court lol put it like under the hoop somewhere. Right in the middle just looks so awkward and unnatural. Unless you're going for gameplay, and not looks. Gameplay wise it's best in the middle, but when for a map thats supposed to look good, naturally, basketballs are hanging out under the hoop.
Just a nitpicky thing I see.
If the only thing I can point out is where a basketball should be, I think you have a pretty good build haha.
