Wow looks like this is for a completely new audience. The colours on your after pic are beautiful!! My daughter prefers the early one though (she's seven) your style may be changing but don't disgard your earlier work it's also lovely!!
This looks awesome. You've improved a lot! I'm amazed at how your sense of color has grown, and you used that purple and yellow in the new one. Your human-drawing in general has improved so much too. Great work.
