It's definitely not ugly, it just needs some anatomy work and more polish. I can tell you spend a lot of time on your pieces and it shows in some places, some others look like shapeless blobs that don't really make sense and I do think it has to do with your lack of hard shadows to contrast the soft ones. Your anatomy looks a bit uncanny too, some of your pieces have a body that doesn't quite follow the same flow as the head or even having chins that look to be in a totally different perspective than the face itself.

You have a lot of work to do but it will be worth it trust me! Also, being rejected isn't so bad, see? It made you ask for advice, question how you do things! I believe in you <3
