What a coincidence. I have just made my first foray into acrylic painting. I'm an accomplished illustrator, working in pencil, pen, chalk, conte, but I'e shied away from paints because I don't seem to be able to get myhead around rendering in colour.
For, now I'm just using $1/bottle craft acrylics. I won't waste my money until and unless I keep this up as a hobby.
I haven't really figured out my technique - I'm waffling between watercolour style - applying transparent washes sparingly to white paper - and oil style, blending and building up layer after layer of opaque colour.
The acrylics are drying too quickly to blend, so I got a bottle of gesso - or whatever they call the stuff to mix in to the paints to extend their working time.
This is my first attempt.
You can see in the upper right corner, where I had to "cool down" the forehead to make it recede.
The flesh colour was dry so I tried to add a transparent wash of blue, but it just looks muddy.
I couldn't redo the flesh with a cooler flesh tone because an opaque redo would never match.
