Yo mate I just wanted to improve some colors for your art and help u out a bit

Description: I added some colors to your art, hope you don't mind! A recommendation- For color, don't go to the extreme colors like full red or black or even white, as they can be harsh to look at. Also, when darkening a color, make it more purple and vivid, and more yellow and bright when you want it to be lighter. This is a cool idea you've got here! I hope your art will progress with time as you're off to a great start here!
