Hi Olga,
I've been reading your previous WIP/SBS threads, and just like all the others I'm kind of speechless by your fantastic artistic talent!
You mention using (or at least at some point you used it, I see that apparently now you are using more acrylics instead) tempera paint.
I guess you mean traditional tempera paint? As you also said before that you weren't using oil tempera.
I just found this, regarding tempera paint, apparently it has been used for millennia! And many classic artist painters have used it in many famous artworks!

The acrylics you use now, do they mix with water, or do you use some special acrylic thinner? Any favorite brand?
Thanks a lot. And keep up your fantastic work of art!
Cheers!
