Today is another logo as a profile picture

As you can see the page is about fashion, so I tried converting the mannequin into a full dress with someone wearing it. Used my mother as a model, although I took some creative licence when it comes to her hair and other details, there are some shots of the process, I’ll leave it like that, this one was fun!

I don’t know how to make my lines better, any suggestions? what kind of exercises are out there?
