A little test I've made to use my newly bought guache!I never used guache before, the only thing I know is that is very opaque, I used for the background and I love how bright it looks, but it was super thick and it came super streaky. i don't know if it was because of my super low quality brush or because it must be used with water..? I'm really ingorant with guache, but I've seen people making super smooth beautiful paintings with it so i'm not sure..

also I love the super thick lineart. I love bold comic like lineart much more than fine one.
