Gj on your vectors Sweethoney. I can see your improving.
I think the things that you can work on the most are the Outlines shapes, the curves. But you mentioned it yourself already. Also the colors could be more vibrant. And some part looks strange due to the blur or something like that. Notable the most at her hand.
Also for the final. Just spend a bit extra time double checking the coloring doesn't go over the outlines. But GJ on your last two vectors. And good luck with your next one.
