Looks good! I know what ya mean about scale though. I'm having that same problem with my entry in the hometown map (yes I'm goign to enter too...since voting isn't biased) I would think it doesn't have to be identical to the original location, just be based on it.
As for thsi thread though...I'm going to move it to the mapping challenges forum...I wanna keep all challenge WIPs in that forum. Judging will of course be based on the final image you post in this thread.
Feel free to edit your post and change the subject so it doesn't say Randolph anymore...and replace it with what you actually wanna title it. Sorry for the confusion.
