From the pic , it looks like you have pretty good form for someone new. I agree with the relaxed grip.
I disagree with your draw being too short. At full draw , the string should be around 1/2"-3/4" past the corner of your mouth and you should have a slight bend in your bow arm , which from the pic , it appears you have both.

Keep practicing , but keep it fun!
