They all look great! But I'm not really a fan of the pictures. I don't like the bloom effect some have or the toning in them. I know they're trying to do an old timey/romantic vibe with that, but I don't particularly think it works. The most interesting one is Vernon's, it's the only one that seems to have more dept and captures the concept well, the others are just pretty bland in composition.
Yeah, Seventeen's teaser photos are generally pretty uninspired It's why I don't let it affect me and worry about the actual song because 95% chance it's not a reflection of it lmao
