Hi, so i am pretty casual lifter, like to hit the gym like 3-5x times a week(not atm ofc). Thought maybe someone who is trainer and knows little bit more, why its fucked up? I usually do EZ bar close grip, hammer curl, dumbell curl and maybe sometimes cables too, but usually 3 exercises 4x10. One person told me that genetics play role here, but need more opinions for that 
Anyway on the first picture is my left hand biceps and other 3 is right. Pictures aint the best, but can see that isnt straight at all
