That's a pretty interesting idea, to have your own logo and a patch to go with it.

IMO the design should be your own, whatever you feel good with. Personally I'd probably make my biceps look bigger than really are, more like my attitude than reality...

One serious thought: not sure which is your "other arm". If I were making a patch like this, I would set it up to be looking forward, so the exact design would depend on which sleeve it would be applied to. Just a thought.
