Hell of a start friend. As young as you are, just keep studying your body and find what works and keep doing it until you plateau. You have plenty of time to compete being so young. Everything looks like it's coming along well and at a pretty even pace. I'm 6'-6'1 and to compete your going to want or have to put on more size, but just keep doing what you're doing because it appears to be working well. As far as trainers and coaches, just study nutrition and read all the training books with methods of training and put your programs together that you want to try and when you are ready it s your choice if you want to get a coach before your first show or just do what you like and think works and see how you do. Dorian Yates, Jay Cutler, to name a couple popular names often times did shows without a coach, especially Dorian, Jay did quite a few also. Not trying to talk you out of a coach, but your pics. say you don't need one to me. My opinion. Regardless, HEll OF A JOB!
