Really love the color palette of your first finished piece!! The texture/linework going on with the animals looks really great! One thing that can be improved is the design of your main character, I feel like her chin is a bit big and you could really simplify the shape her face for a stronger design. Maybe just let her face round down to the neck or keep a small pointy chin?
Felt like it would be easier to just show you what I'm talking about so I did a quick paint over of the examples. Hope you don't mind me butchering your lovely work! But obviously if its part of your style and you love it the way it is then go with what you like
Also I added more volume to her hair where the bird is so the bird feels like its sitting in her hair. Cant wait to see your next finished piece!
