I've been having a lot of idle fun in the past few days, playing with the Paint.Net program. It's fun, it's free, and (I think) it does most of what you might want.
This is John Everett Millais' 'Venus Verticordia' (Venus will turn your heart vertical). It's a winsome, bee-stung lipped nonsense, with slight symptoms of thyroid trouble in her neck.
Here, on the other hand, by Hans Memling, is an old lady who's seen it all.
She ain't going to take shit from nobody.
But this is the best, the Rokeby Venus, by Diego Velázquez.
Truly, Venus in Blue Jeans, and one of the best bums ever painted.
