I think you may have posted this in the incorrect thread.
Anyway, I see maybe an ever so slight asymmetry, but to be honest, it looks fine; looks like any other BvS Supes. What it does look like though is the sculpt needs to be very slightly turned to the left if you're going for a straight on look. In addition, I think the way the cape wraps around the neck on each side actually helps give the asymmetrical illusion more so than it is the actual suit being off. The cape on his left shoulder stays more on the lining of the collar of the suit, whereas the cape on his right shoulder comes off of it and wraps around a little closer to his neck. Something I've noticed that most of the BvS figures I've seen do.
I wouldn't let it consume you. Your figure looks great.
