I can't say that how you designed (or the tattoo artist interpreted) this symbol/tattoo was really well done. I say this primarily due to the fact that there is very little shading work (if at all, since it seems this way from the camera shot), the dimensions are slightly skewed, there is no noticeable use of colour or variation in hues or values, and there was little line variety.

In many ways, it looks akin to that of a whimsical pen-drawing upon your skin.
