@allysa I've noticed your images take a VERY long time to load on your website. Did you resize them and optimized them for web? When I try to click on images to zoom into them, sometimes it works and sometimes it doesn't. The website is very buggy and sometimes displays like this:
I would also add a contact page or at least a contact form on your about page. Right now the only way to reach you is the tiny letter icon under your photo, and it took me a while to find it!
Apart from that I agree with the others - you have a lot of technical skill, but your work seems to lack a little magic, charm and relatability. You could improve your facial expressions and storytelling. You don't have any interactions, all the characters are alone and that's a big gap. Look for the little detail that makes it real - two characters sharing a look with a sparkle in their eye, a little touch on the hand, not knowing how to help, or the proud look a father gives his daughter while she happily plays, oblivious.
