submitting 2 so similar photos, gives your name away. I suggest you delete one of them, or you will find that both get removed by Mods.

Great shot!

I don't think it makes any difference if two images are close and I don't see how it gives your name away either. I've seen it a lot of it in contests and they stick around to the end. (i.e. “wearing purple” photography contest. There’s two entries in that contest you can tell they were the same person) I also saw it with another but they changed it up enough that you don’t notice. However, they are pretty close as far as theme match and I can tell the previous was yours as well, maybe a bit more diversity with your entries. I like this one more though. It looks great in high res.

it depends on when you place your vote on them........if you place one, then you will see the authors name afterwards, and be able to tell the other from that.
