Could use a little more weathering.
Like, that jolly-boat actually looks perfectly usable, which belies it being turned into a roof. If it looked more worn, it would make more sense that it had ceased use on the water. Also, it seems iffy that the stand's wood and the boat's wood would be equally aged - did someone build a ramshackle stand with a perfectly new boat as the roof? So maybe just wear the boat more and not the lower part of the stand?
Love the overall look though.
