U could used different armor shell pieces on different limbs. The asymmetrical look is pretty easy to get with this method. But let's give you a tip: never, but NEVER use different sized bone pieces for the legs. Once I put a different sized bone piece in one of my moc without realizing this, and I tried to put him in a decent pose for like a week, but that stupid piece was not helping. I pretty annoying to have a moc with a longer leg, especially if you want to pose him.
And also, next time can you reply to ME when you want to talk to ME?
