I like the way you tackled your project from the creation of the clothes using Marvelous designer and in particular your Z Brush skills. A few additional extras like a gun belt under the coat and the buttons and holes or even a collar would raise the design further.
A good attempt at a human figure push the uniqueness of your character to give him a real personality and think about how to use the clothing to try out different techniques.
A nice piece of work with a good use of colour and stylised approach. It is a big improvement on your first piece but you should include your Dev work to show the full dev process and document your development. Good to see your continuing to grow as an artist and are gaining skills. Well done.
