Not a big fan of the prescription glasses on the mods.
If they're supposed to be sunglasses, the lenses shouldn't be clear.
While I like the theme, I'd personally prefer something more exotic, like palm trees, a tiki bar, a jetski, a water skier, parasailing, beach volleyball, or a mask & snorkel, or you could add a kite. Something like that.
The parasol would look better at an angle imo, plus I'd add an accented blue key variant.
