Working on Tower Defense game based on J.R.R Tolkien and Warcraft worlds

I’ve got the basic code done to run a level… just need to expand it for multiple levels, cut scenes, ect.
Doing the artwork myself at first… not the best looking, but I have to learn perspective, shading and highlights, and a lot of other stuff. Let me know if you know of any resources to become a better artist!
