Hey, you look good for a 17 year old, not sure what type of feedback you are looking for. But I feel that although you can compete in the teenage division as well as the novice, I still feel you could still add some muscle first. Meaning taking sometime to put weight before starting your prep. Most likely, if you diet down to where you need to be to compete, you might realize you don’t have enough of the lean muscle mass you’d want for a contest.
