you could add some wildlife like a crane or some other kind of bird to it. I would also add some really subtle background to it.

The idea is a good start, but the flag could be way more interesting if it actually had some movement to it. And forget tattooing a sun with any kinda detail super small like that.

looks like a normal heal to me. The very top layer of skin gets damaged by the tattooing process and will die and fall off. This is completely normal. The white ring is just the edge of where the top layer is pealing off. Another week to a month and it should all be back to normal.
