Can up with an idea to help with the overall "cartoon" look to project. By using the original textures and applying a "toon" filter in photoshop I came up with this
The Original File
Now with the TOON Filter applied
There are loads of setting with the plugin I used, this is just one of them
This is the plugin I tried but if used we can look for one we could all use that's free, LOL. There is a free trial so check it out.
