The overall shape of the plan is from the keep of Caernarvon Castle in Wales. I have a couple of books of castle plans that I often reference, unfortunately the plans in the book are extremely vague so I take a great amount of artistic liscense in creating whatever layout that suits me. Starting out with a general outline that I find pleasing is a common technique I use when creating plans. In this case, I didn't stray too far from the original inspiration.

As for the trees: They are intended to be symbols of the tree's locations, not actual artistic renderings of trees. I purposefully made their outlines bold so that they would stand out against the plan to avoid any confusion. In drafting it is more important to maintain clarity and legibility than seek to maintain artistic quality; I guess old habits are hard to break lol.

I did forget to mention that this is hand-drawn. No digital editing has been done other than to patch together the multiple scans of the 13"x19" original. I do plan on using Photoshop to add text and to do a little "cleanup".
