Brilliant stuff.
The amount of attention paid to minutiae (such as the woman's hair) is something to applaud. The contrast in skin color is interesting- a most successful portrayal of "porcelaine white", methinks. The only thing that seems odd/out of place versus the remainder of your rendition is the tattoo. Somehow it seems a little odd (e.g. angle vs placement, vs arm muscles).
Keep at it,
