Chimney boot doesn't look correct possibly a through the wall setup for horizontal not vertical, no chimney flashing, should have guy wires so it doesn't blow over in a strong storm
Think I'd do something a little different with all those clip on battery connections. One little mishap in there and that cabin is a pile of ashes.
Need a much bigger wood shed and cover it from the elements! Need to add a dry room on the front entrance, keeps the winter from blowing through the door when ever you go out, plus makes a place to dry your outside clothes. Ideally, your wood shed would also be accessable with out going through the outside door! May also wanna stash your water cashe inside that dry room, keep it from freezing! Rigged properly, the heat from inside would melt just enough snow to keep your water level up!
