I’ve darkened some of the foreground trees today to push the farther ones back into the distance more. This also seems to emphasise the sunshine, although I should have left more white spaces amongst the higher leaves as well.
It still needs lots more work – the undergrowth on the right hand side needs more detail, and the foreground could do with some sort of creative leafy, scrubby, soil and stoney stuff. I think I may darken the upper branches too, somehow they all seem to be fading into nothing and they should probably more contrasty against the bright sky – sorry, I think I made that word up :-).
