Well One of the most difficult aspect when I make a illustration is the color. As you see my technique is very experimental, I started this picture with gradient pink-purple background and I decided to change it some steps later. The select colors and how to use it into a digital art has a lot of topics and teorical aspects, so If you check my next posts of step by step drawing I am going to talk more about the selection of color and why I use some palete. Thanks to make this question, is really important! I will focus in this theme. Thanks to write me, I really apprecite it!
