You need to source the original painting as well!

Uppss!..thanks for telling me that..I'll do it right now

I would say that the head looks to big, but this is Lady Gaga so the image should be a bit out of the box like herself

HEAD TOO BIG!

Fixed the head..
i think make it a little more small, would be unreal..
but there it is.

Good choice. The black values on Gaga's face are too dark for the rest of the image though. If you lighten them slightly (Image>Adjustments>Selective Color>Blacks) to better match the darks of the painting, it will be more consistent.

Thanks...MossyB
made that change,its much better!.

The black lightening bolt is still the darkest, least noisy element in the image and thus does not seem part of the painting. More problematic is that a Renaissance Lady Gaga would change not only her hair but also her clothes. Wearing male military attire, for example, would no doubt have seemed outrageous at the time.

head too big???
