Create a low poly rigged 3d character

Hi, I want you to create a 3d character from my attached image and details for my mobile unity game,
the changes I want to make to it are:

1. change waist coat to leather texture and make it cover his nipples
2. remove naval, as want the vest to not be see through
3. add gold belt buckle (square with no center pin)
4. make chin less pronounced
5. make bottom lip smaller
6. make eye brows less diagonal shape
7. add black boots
8. add small finger band style gold ring to right hand
9. colour the model

Ps, I don't have the character model/textures, only a image of what I want making :)
