do my colors look good? updated.

[meat]

I've no idea how tattoo art works, but if you're looking for popping, you could even add white highlights to, especially, the metallic parts of the image. Or even the lady herself, although her skin might look oiled. I'm saying this because you have a lot of pure black, so the opposite of that is pure white highlight, which could work in this case, but in controlled small amount, and strategically placed to make things pop out. Give it a try and see if you like it.

Another thing is the lady's boobs are too far apart. They also stick up too stiffly, and too spherically (especially the left one). Boobs behave kind of like, ladies of this forum please don't kill me, sacks, when they're natural. They do... drift apart in the end, but they're still close on top... if that makes sense. So, reference time!

The newest issue of ImagineFX, if you have access to it, has an article on tattoo art, which you might find interesting to look at.
