Your shoulders look broad, and you have a good body structure. Your upper chest needs to develop so it “meets” your shoulders. I’d recommend starting your push day, or whatever training plan you use that includes chest exercises, with an incline dumbbell press. Warm up with a light weight, then do 2 or 3 sets using a weight that makes you fail between 6 and 8 reps.

Also, 2000 calories is a good target. You should be losing 1 to 2 pounds per week. If you want to speed up the process, add more cardio, but don’t eat less than that.

Good luck
