Acryl-gouache

I love bright colors but in this case I want to change the palette and try with softer asiatic colors. I will be working with acryl-gouache because I received a box as gift and it would be a crime not to use them because they have been standing at least 3 years. They tend to dry very fast so I will make a big amount of the base colors and use a retarder (you cannot use them again when dry as gouache).
Maybe I will pick the mint-purple colors. Jeeeee

Robot sketches

Here I have some pencil sketches, feel is too much information and I think they would work better if I made a simple illustration book.
