Like this, and presume there have been no comments so far because everyone's away, out on the beach, or lying, groaning, in a darkened room with cold compresses pressed to the forehead. Nothing like the same or even similar, is it, painting in acrylic after being used to oil? You're working at speed (not that there's anything wrong with that if you can keep up the level of energy required) probably because you're using oil painting techniques and the paint is drying on you however quickly you apply it. I can only work in short bursts because of physical limitations, so that wouldn't be any good for me - while I could work in interactive acrylics, obviating the problem, I've found you can work in a multiplicity of layers in acrylic, glazing and scumbling away to your heart's content (I've also found that blending is nowhere near the problem in acrylics that some insist it is). Maybe try that approach - although not because there's anything wrong with the one you've chosen, it's just another way of doing things. I like the composition, directional lines, contre-jour, and freshness in this - rather a lot, actually!
