You seem to be applying a sort of understated/greyish vignette? I think it's pretty effective on the first one, but outright damaging to the second -- let that stuff on the right go down to black. I like black, so this is partly a personal thing, but also I think there's texture over there that's not adding to the picture. Pushing it down makes it less intrusive.
That's a minor quibble, though! I like #1 and #2 quite well.
