Hi Scott,
Welcome to Permies!!!
For a first attempt and getting ahead of yourself, it looks as though you have done very well. Many a "homesteader" will build such a vernacular structure to get started (and learn) while the "feel" their way around the
land. Then they can build a more enduring and permanent structure. Again welcome, and we all will look forward to following the progression. Thanks for sharing the photos.
Regards,
