Since I retired from the military I have changed my appearance several times via beard growth.  Full on untrimmed beard, trimmed full beard, goatee (current featured picture), or babies butt clean-shaven?  Which do you think is best for me?

This is full trimmed beard in October,

Full Beard in December, pretty much non-trimmed,

Or a very grainy photo of me in September completely clean shaven.

Just wanting your opinion.
