Seriously nice ink.
What would I have done differently?
Most likely, I probably would have screwed it up. You done real good.
Maybe have the model oil up - the oil adds a bit of intensity to the color. But the sheen of the oil can be difficult to handle.
I have a bit of a problem with the intensity and detail visible in the background - maybe give it lower light by a stop or two, to darken it, make it more like her skirt - but not quite so black. Or maybe - if possible - have her use a skirt more like the background.
Second shot - you done really real good.
Thanks for sharing.
