Original Description:
 
My last picture of 2021 and the first that was totally colored in Paint Tool SAI (except the floor and the pool). It was a picture in which I could test many SAI functions and improve my coloring style. I still have some more tests to do, but I’m quite happy, satisfied and proud with the result. Not bad for who uses a mouse to color pictures XD
 
But that’s it, my pictures will look like this from now on.
