I'm no expert, but an easy way to determine short or long draw length in a pic is to notice head position. Your head position seems right on to me i.e. not leaning forward to get to the peep.
Please help me out on this. Is the head position a good way to determine draw length by looking at a pic of someones form?
Head positon is just one piece of a giant puzzle.
I have a friend who is also a level 4 and he would not set your bow arm up that way.
Discuss it with him,I am sure he will let you adjust to fit you better.
Like I said earlier,it looks as though you could straighten it out more at the draw that you are set at now.That would really load that shoulder though,if it worked up on you,then you would know you were too short.
My friend would set your arm up more like this.

Check out this pic,it is the EXACT same bow and draw length.And the same release as the second pic.
