Ive seen guys with amazing bicep developement and no tricep mass, he looked like shit in general, the only time arm looked good when he had his arms down and were palms facing front, turn the guy few degree and show is over.

I also have seen guys with minimal bicep development and huge tricep mass development and that arm looked amazing big, tricep fills an arm so much and almost seems it brings up bicep and gives illusion of bicep thickness.

And where guys had worked out tricep to a higher degree than the bicep but still bicep wasn't lagging either, now those seemed like they were the guns that resemble of guys at the top level.
