That's kind of my point...the overall costume seems very old-school compared to the previous movie outfits with their raised webbing and whatnot, so it's an odd choice that they'd slap such a flashy upgrade on it as the expressive eyes. Other than the eyes, this one looks the most like something that Peter might have credibly made himself if he had a really good home ec teacher...so it'll be all the odder (in relationship to the previous movie outfits) if he had Stark's help with this one...whereas his previous film outfits were presumably made by Peter with no help, but seemed beyond the capabilities of a teenager to make in his bedroom.
Comparing this to those doesn't make much sense to me, though, since it's a different reality playing by different rules. The whole idea of having Tony provide the final suit is a direct response to those criticisms, by providing a rationale for a 15-year-old from Queens to have a movie-worthy costume. And a costume doesn't have to be loaded with all sorts of fancy textures or gadgets to be high-tech. There are a number of subtle details that are beyond what a "home ec teacher" could explain, like the fine texture of the material (which is still there, just less pronounced than before) and the details on the belt that are presumably web-cartridge holders. I'm sure we'll get a look at his high-tech Stark-made webshooters as well. (Now, that's a question. Raimi's Spidey had organic webbing; Webb's stole the web formula from Oscorp. Will Marvel finally go with the idea that Peter Parker was brilliant enough to invent the web formula on his own, or will they cop out too and say it was a Stark invention? I'm thinking maybe Peter invented it, and that got Tony's interest, but his own webshooter prototypes are probably cruder and bulkier than what Tony provides as part of the final costume.)
As with all things in movie trailers, it's reckless and pointless to try to make decisive judgments based on a couple of seconds out of context. We'll get a better idea when we see the actual movie and have more than one little glimpse to go on. How often in your life have you been felt initial dislike or skepticism toward something -- or someone -- that you learned to love once you had more experience?
