Use the stick, overbrush a base coat. Use Foundation paints for your base colors when you're going for speed. This is a tan over black; I'll wash some depth in later.
Add a bit of a lighter shade, overbrush, add a bit of a white, overbrush. Don't clean your brush. Use a large brush - you're going for area here, and the mini doesn't care if you're using your sable brush. I added a yellow on the beak, brushing hard near the tip (heh) and light near the base; again, I'll wash depth in later.
Blue near the base, same as above. Add a lighter blue - again, don't wash your brush unless it needs it - then some white... overbrush... you're going for a drybrush type look on the blue area.
Purple. Then lighter purple over that. Then take a bit of light blue and sorta brush near the join of the two colors. Don't sweat it too much.
Wash the rest of the model with a brown wash, beak included. In this case, I used Sepia, not Mud. Don't be afraid of hitting the purple area; in fact, purple loves Sepia. Hell, do the whole model with the wash, if you want, assuming the other wash is dry.
I cheated. The brown fur is an old-style ink. It goes on easy and you're gonna matte finish it anyway - you want speed here.
I start hitting the details here, some white on the stubby bits. Green for eyes. Green for hands. Notice I build up the green in the same way I did the other colors. Base with big brush, lighter color, wash, lighter color over to bring up the highlights.
Hit the green again, after the wash drys, just like I said before. The only time I used a small brush was the eyes.
All four models in one hour. Then I based them, which actually took about 15 minutes or so, but a good base improves an otherwise blah model.
