As the others have mentioned, he's pretty much done growing for this year. Also, he does appear to be an immature buck, certainly no shooter.
Not in IL, but let me tell you . . . if you let bucks like that go here in eastern NY, and assuming you were an excellent
hunter, you would proably get a larger 3.5 year old buck once every 10 years or so, maybe longer. I probably would pass that buck, but the reality is, you have to hunt the bucks you have. The reason I go to IL is so that I can pass bucks like that.
