My goodness, this one is quite a task. Not really the difficulty of it but the amount of work, specially beforehand. The gesso bushes/forest (white, grey black) took quite some time if you really wanted to create a descent forest, which I think is really worth it. The very small trees, or hint of trees, are to be done with a pallet knife since even the scriptliner can be too thick for that. Bob does not mention that in his intro however but I'm pretty sure he might've done it that way as well since his are about perfect straight lines. Stones in the river .... I had troubles since not really skilled enough for that, so my riverstones might look more like cubes iso marbles. :) I tried a little indian yellow to mix with the blue in the forest and that really gave a nice warm, yellow/green shade. I dared not to use a lot of it though! The rocks on top and the waterfall are amongst the easiest things to do here, so I created a major wall on the right side to show some power to the painting. Well, at least that is my opinion. I decided on a much larger waterfall, which is okay but then you need more foam and water sprinkles (see my article!). The leaves were quite a big challenge to me yet taking enough paint on the brush, tapping more carefully then ever and hopping around between four colours (yellow, green, oker, red) really gave some body to it, specially with drawing multiple little branches afterwards (scriptliner) which give quite some depth. The attempt for water was almost futile yet with highlighting it with some white (and a very little blue), it became what it was destined to be. Keep in mind to overdue the white lining a little on the sides, meaning go a little OVER the rocks on the side to create depth and water illusion. In all, an afternoon VERY WELL spent with a great result, I dare to say. Have fun with this one everyone!!
