OP, if thats you on the left, you're likely the most developed out of the three but please learn to pose before stepping on stage ffs. Its a tiny investment compared with everything else. And honestly from that one picture alone, the guy on the right wins that pose effortlessly.
Difficult to compare muscularity since you're both doing different poses but he's keeping his torso in the proper position to keep the lats flared instead of dropping his chest like you for more visible abs. A front relaxed is for overall balance and "stage presence" which NEEDS you to look wide and tapered. Dont dip your chest to deepen ab separation, this is the wrong pose for that and youre not naturally wide: use the ab-thigh to show ab separation, and don't dip your neck to pop the traps annd front delts up in the front relaxed, you can look down in a REAR lat spread or rear relaxed to pop your traps out. youre essentially doing a hybrid and losing points.
Also (IMO) dont use the bow legged pose to show your thighs as you could get marked down. Your quads look like a strong point so you dont need that.
