I should probably do something about the rather harsh posterization going on in the Lady Venus shot above. Pushed the colours quite far in Lightroom. That's the one thing I miss in LR, the ability to easily fix up things like that with a lasso and some Gaussian blurring + noise/ dithering. I'd probably also burn down the left hand side to balance the more polarised dark sky on the right.
I love what the polariser, combined with the bright desert sky and low angle is doing in the ghost rider shot. I did drag it a bit further to the dark side too, feels like it fits with the theme.
