When painting the foliage make sure that you use a dry brush technique and that you use this to break up the harsh rock formations that you have created by simply pressing the brush down against the rock formation. Make sure that you don't segregate the areas in the painting. Make sure that you blend the areas together to make the picture complete. You want to take the warm, more contrasting areas and use them to break up the harsher style of the rest of the picture. You want to layer the colors and allow the colors to bleed through in an overlapping technique.
