These will be made to order. The amount of shading and/or color depends on what you want. You can be as specific as you want- whether it be a certain mountain range you'd like in the picture or what colors you want used, or something as simple as "3 mountain peaks with the moon peaking out". I will reach out with a simple sketch before starting burning to confirm you get what you want.
 
Example: for the third picture, customer asked for watercolor and asked that the sun shone through the mountains and reflected off of the snow-capped mountains.
