I wouldn't class them as fair usage, but that doesn't matter since they are not being monetized. The thing is when I first looked at your channel, I thought that the thumbnails were standard non-custom thumbnails from the actual video. It's up to you whether to wait for more viewers or not, but it's like VoltageDSG said previously - he got your same email initially, reapplied in a few weeks and got accepted.
They are being monetized my youtube is linked with my adsense account, most people that make vids similar to mine make thumbnails with a wrestler in and then a nice background and that is classed as fair usage so shouldn't mine be? Do you still think a network will take me on?
