hey Bro!
Unbelivable legs man. Great balance/shape in quads/hams and good balance with your calves!! No, question your legs are your strong point.
I got to say that the tatts obscure your entire arm and it is hard to see your triceps. However, your bicep is full and has very good shape. If I were judging I would say that your triceps are weaker than your biceps so work your tris harder to get a little more mass to balance out your bi's.
It is very obvious that your back is your weakest part. It looks like the tie-ins are good genetically. It just looks like you haven't worked it as hard as your other bodyparts.
Upper middle chest needs some thickness.
Hope this helps, bud. I hope that I wasn't too critical, however, you asked. Overall, you have an excellent physique and excellent potential for national shows. Just work that back hard, Bro and you can go far!
PM me if you have any questions. I think the arm tatts will hurt you because the Judges won't be able to see your arm musculature.
