Well I believe cropping is all about personal preference. They say there are rules like the "rules of 3rd" and other stuff. But like I said I like what you did, and you did an amazing job with your PP.
here my quick attempt on cropping.
I would usually go with the square. I've received a lot of critique before that I need to crop tighter so it will be more personal.
a tighter cropped portrait orientation is good too
sometimes I would also do landscape orientation but since the subject is not really isolated to the background, I would just crop tighter with your photo to avoid distractions.
here's my favorite sample

But like I said it's all about your personal preference, all about what you like (: (Unless you're being payed to take pictures.)
