Tutorial: Forest deer girl Picture

I decided to make a tutorial out of this one, it was my first attempt at a background and I am pretty happy with the overall painting so I thought i'd make a step by step so that others could see my process and hopefully it can also be helpful to someone. I'm not sure if my explanation is very clear but I hope it's good enough to understand what I'm talking about.
