like it a lot, but I think on the black you should remove the gold scratchy pattern stuff there. the little lines and whatnot. Just make the black a normal marble texture, the little gold marks adds just a BIT too much

It may be a little too detailed, but it's a good skin.

Hey, you asked for feedback, may I say the following?

So I love the red/blue texture, however the black one is too much, rather because it is too busy, you need to only have 1 busy texture in order for your skin to not contrast badly, so try to make it a solid color

This is a very good skin, nice work!

Miss circle skin o algo
