Thank you for the kind words!

As for the software comment, unfortunately, I am not really interested in any software assistance (when I eventually write labels they will also be hand drawn etc.). Perhaps I'll experiment with dotted lines next time or a different color (brown or brownish red).

Per the elevation lines, those two "horns" are the actual water flowing from the springs into the pond. I forgot to add spring symbols but I didn't really know what to use to indicate the actual spring.... ideas?
