Amazing work @darklightillu. Acrylics can be used in thin layers like watercolors, or in thicker, more opaque applications of paint, like oil paint. Acrylics dry quickly and can be diluted and cleaned with water, making them simple to use, odorless, and accessible to all.
You have beautifully shown different steps of painting in your post.
Definitely its a great art that requires different skills as choosing a brush, palette, and canvas. Altering acrylic paint with water and other mediums, Blocking in and underpainting, Adding glazes, Choosing pigments, Understanding basic color theory, Creating texture and so on.
Just following you to see some more great posts.
