Watercolour painting "Winter Farm Track"

The sky here is my usual Raw Sienna wash with some Ultramarine blue visible through the clouds.  The only thing I did different here was to take out some more clouds with a scrunched up tissue just above the horizon.

I think one of the easiest ways of ruining a painting is simply overworking it.  One of best pieces of advice I heard was don't paint over a previously painted area unless you have a specific reason for doing so.  Every stroke of your brush should count for something.  The temptation to do too much can sometimes be overwhelming.
