Character design for adventure project

This is my character design for my adventure project. It is a cowboy on a WWI horse. I started to make my character on Adobe Illustrator by getting pictures off the internet of cowboys on horses then I added a flamethrower and a horse gas mask from WWI. I then drew a outline of the design to make it look like it was done with a pencil. I also made the background grey. The next part was to start using dark colour tone to give a shiny look to the horses fur. I then started to shade the areas that were dark.
