Things to take into account during further steps:
1.- When I add the second layer of purple on the glasses' crystals everything under it will probably blur a tiny bit, gotta be careful with the values and not mess that area up.
2.- The black of the glasses is just the base coat so the value will be darker in the future, gotta darken the value of the glasses shadows before adding the final purple wash of the crystal if I want it to be correct, since both glasses and shadows will have to be close in value.
3.- Beware of the pink lipstick effect Teresa!
4.- Fix the bag under the left eye, it was correct in the monochromatic version, be bolder with it.
5.- Gotta fix the shape of the chin, it's a bit off, and have to adjust the color of the shadow under it.
6.- Gotta add the beard and mustache asap, this guy looks pretty
7.- Approach to hair/background/clothing on hold until next round, don't stress over it by now.
Irina, here you have a shot of the palette, my setup of the colors is pretty random but it works for me :), not too much going around right now since I'm almost layering pure thin color for the 90% of the painting and I'm not needing big amounts of pigment by now, when I start with the background/hair/clothing things will be different, I'll upload another photo then, ok?
