"Harvest Moon" WIP 5

I'll keep the number of color tubes used low for a few more pictures - with this one I'm learning a lot on how to control saturation and hues but I'm still not very comfortable with mixing desaturated colors from more than two colors (plus white). Most of the gray areas area a mix of phtalo blue 15:3 and cadmium red with a small addition of yellow ochre.  Working with two main colors to get the grays and a third one for fine tuning seems to work well.

I'm keeping the owls on the trees slightly out of focus to suggest distance too.

On a side note, how cool is this incoming movie?? It's about time for owls to get more love from the media. :-) Don't forget to give a caress to your garden's owl today.
