Wonderful portrait. Captures the feel of the original Boldini while doing some genuinely cool stuff with colour. Love how you've resolved the line detail on the evening jacket.
Well sir I must say you're absolutely correct 
. I made a few quick changes to try and get it to work a bit better.
Adding the black is a nice change, the higher contrast works nicely overall. I think the bowtie got a bit lost due to the bright highlights on it.
I like how you combine pixel with impressionism. Very pleasant
