Concept Art: Troll Body

After creating the faces for both my characters I wanted to understand how the body would look from the front as well as finalize some details about her appearance. the problem i faced was if she was going to lead forwards so much that she would be hunched as well as if she was going to be fat or thin.
after looking online most trolls were either very bulky or quite fat especially around the stomach so taking this into consideration as well as her age range I decide that the bottom two forms would be most suited.
i also had to consider her clothes and eyes.
I wanted to understand what she was wearing and why so i made a quite back story which incorporated the descriptions from the official book.
the story was when she was younger, she wished to be a respected princess but there isn't many supplies in the territory to have the dress she wants. so after scavenging around the edges of her territory she finds a beautiful pale yellow dress she tried it on and feel in love with it. over time she has grown and the dress is worn and shredded but she refuses to take it off because for her the dress is a princess dress broken or not.
so as i go through her costume especially when it comes to the model sheet I will try and take into consideration of what her dress used to look like and how it would wear.
I wanted to pick out her eye colour to reflect wear she lives (mostly in caves) so i did a bit of scientific research that the lightest eye colours take in more light so I was looking at either blue or green eye colours.
