Well, I am being realistic that the quads need to be in balance with your calves. If you bring out more spearation and detail then maybe that can help? My thoughts would be brief rest between sets and high reps like 12-25 reps.
Of course, I am somewhat guessing.
You have awesome arms, impressive lower back, hard upper back, massive calves, great upper abs. I think alot just takes some more time. Maybe change your training since you have the size you want? I dont know. What do you want?
