personally if that was me, i'd take that truck right back to the tint shop. any professional enough tint business would first off... show you an example of the shade of tint you're asking them to do.. and any true reputable shop would suggest to you that it wouldn't match, at all.. and should have suggested something else.
obviously they just wanted the business, did you say anything to them when you went and picked the truck up? nice and clean looking X, but the tint looks bad bro!... I wouldn't rip it off though, take it back and see what they can do for you...
A friend of mine tinted his explorer.. it has the bronze tint, but it doesn't seem AS mirror-ish as in your picture. anyways he threw on some 35% on the front door windows and its obvious it doesn't match, but it doesn't look too bad and NO where as off as yours.. it's not black, it's more of a light smoked out color with a minor mirror/metalitized look to it. that really fits with the factory tint. have the shop tint the other windows to match, or have them remove the 20% and try a differant shade, or even a light mirror tint.
i'm not a tint expert what so ever, but i've done it myself on all my cars and i'd say it's definety a PINTA job and for the $150 ish i'd let the shop tint the rest of them, rather than doing it yourself, you'll spend $50-60 on rolls of tint alone, and a good full day to do it right.. and don't forget the stress factor LOL. and this way if it gets screwed up, you blaime them.... not yourself HAHA. because nothing is worse than those tiny tiny air/soap solution bubbles and peeling corners that are all too familiar with DIY tint film... even high/pro grade film if ya don't do it right.
if you DO do it yourself,, i'd definetly ask around a little more- even if you see an explorer (with the bronze-ish factory tint) that has the front tinted out... and it looks decent.. (it's possible, ya see em around all day) ask the owner whats up with it.. forums are great, but sometimes it's best to see what ya want in person! some tint shades can look great and like they match on the internet,but actually horrible on the streets. definetly, definetly take that truck back to the tint shop and don't get off there case till ya get something out of it.
good luck though, sorry for the long reply! i just hate to see people screwed over by business' (not just tint joints) who should have told them how it would come out, before they even done the work!
