I have edited to add something about your draw length.You are slightly higher but I see no problems other than maybe causing some shoulder issues as you get older.A longer loop by an 1/8" MIGHT do wonders.

I am noticing a little bend in the wrist.Try to straighten that out. Notice how matt and I have a straight line from wrist to elbow but you have a hump.It might just be the shirt,not sure.
