Gal, yer working too hard in the mid ranges. That should have taken an hour or so. Now, don't git all defensive... If I can't say the truth I'll shaddap. In acrylics you normally start with the darks & work up. Yer doing everything in the dark to mids & working too hard. Still gotta add in the warms & work up into the highs. The lavenders, the greens, the yellows. Keep yer brush strokes to a minimum so textures don't cause probs.
