The ripples and smears are just the slip solution (Dish soap and water) used to install the film. Leave it outside for day and you should see them go away. You will notice they are less noticeable around the edges of the windows and rubber seal as those should be heat gunned so drier than the rest. They may have a bit of the rainbow effect as thats the soap. You should not see large amounts of water in the windows but they will appear foggy. What you do want to look for in a good tint job is, no scratched glass on outside from cutting. They may have plotter cut it and if so no worries then, but if they hand cut the patterns then they need to be extra careful. The glass on a S scratches easily. I use a special trick where I can cut it on the outside of the window through the film but not touch the glass. Its a trade secret so can't share how I do that though LOL. The next big thing is contamination. Check the corners and look for what appears to be small bubbles. It will be easier to see them once it dries but important to fix them before it dries. This is from dust/lint that gets in during install and can be reduced or eliminated mostly by a good tinter. Its what sets the great tinters apart form the average joes. If not worked on with a hard card before it dries it may not go away. Everyone gets a bit of contamination its taking the time to work them out with a heat gun and hard card that makes the difference. Because the S has frameless doors you have to look at all the micro gaps left on the glass. It should be no more than a 1/16 of an inch. Some shave them so no gaps but thats a lot more work and a bit risky as some may peel back if not perfect. If its computer cut on the doors I have never seen those done well. Just too hard to make a perfect template and no 2 windows are alike. Hand cut is custom and a clean smooth cut with equal gaps is a good tinter. Hope that calms your nerves and helps you a bit and if you get a chance post a close up and I can tell you if its a worry or not. Smears is subjective and if its not the hazy foggy look I think your talking about then it may be of concern. If working out contamination or overheating and pressing our the film you can actually smear the adhesive. That would be very noticeable though and stand out to the surrounding areas quite distinctively.
