It might just be the picture but I'm not seeing a wash on these miniatures. I'm not an amazing miniature painting artist, and I was self taught. So if this sounds dumb, just ignore this post.
I usually paint a base coat (darker colors than the finished colors you want), then I use a watered down black paint wash (to bring out the detail, Very important!) use your brush to apply the wash and soak it up if you put too much on, followed by a dry brush of the colors I want (this step is when I paint in all the details and give it color, use your finest brushes if need be). The results are great! And its easy and quick to do.
As for eyes, I hate eyes but they will make/break a miniature. Try filling the whole eye with black. Then run a off-white line across the eye (----). Then run your brush with black paint perpendicular to that white line in the middle, essentially making a cross with the two colors. (--I--). The results is a black eye ball in the center of a white eye. Its not great and there are better more challenging ways to do an eye, but it works good enough.
I hope that helps and good luck painting.
Thanks. I've tried several different techniques in the past (and continue to try them). I have never been able to get the hang of a black wash. I have tended toward doing straight layers, with some dry brushing for textures. But, with so many bones to paint, I am definitely trying new (& old) things.
I have tried the above "eye" technique as well, with mixed results. A little better results when my own eyes were better Depending on the mini (a couple of these last ones had very small faces, with cloaks covering even more), I have been shooting for just a dot of color to hint at the eyes... which doesn't look as good with these close up pictures, but looks good enough at tabletop viewing
