Banners need to look like a banner. If they look too much like a clickable pic then it is considered a blind link since the surfer thinks that they will be getting a big pic, not a paysite.
The pics aren't that bad, but they are a bit grainy. Some places might not accept them, kind of depends on the mood of the reviewer and how much of that niche they have gotten that day.
Yeah you can resubmit
