I've got all my windows tinted to 20% and the entire front windshield tinted 30%. Yeah it's illegal, but in the 4yrs I've had the windshield tinted, not once have I ever been pulled over for it (and when I have been pulled over for other reasons, still never a word said about any of my tint).
Did have a buddy once with a 4dr F-150 and he had all his windows tinted 20% including the entire windshield. Ha, he got a ticket within just 2wks of having it installed.
Granted, your side windows are much darker than mine, so that in itself may draw extra attention towards a tinted windshield in your case. Still though, I'm always gonna be that guy that votes you tint the entire front windshield. I just think the overall appearance of any vehicle looks much better when every single piece of glass is tinted. The tint just seems to flow better that way.
