Custom Line art from description and sample pic of PIG

Simple line-art with detailed shading for depth + *background gradient of my choosing *Unlimited revisions until I'm happy with the final product. Will send image example that I have added details to and notes so you aren't guessing what I want. However, the example is only to be used for interpretation and I expect custom art created. I don't wan't the image overlaid with a few things and that be it. I wan't your own custom flavor & touch added to make this custom piece. *Looking for things to be proportional to the example, the colors the same and where they are on the image. The bold outlines throughout are also to stay similar. Although I am looking for shading to add depth, I'd like to see the image before shading and after to see which one I like. Would like made it vector for future changes, but also large pixel PNG (2048x2048)
