i don't know about you, but do you think the lifesavers are a bit too big ? cause i think especially compared to the door they seem pretty big (maybe it's just their placement in the scene, though ?). if you think so, as well, i could scale them down a tad, if you want.
other than that you're progressing really nice, i think some better texture variation wouldn't hurt here and there. looks rather uniform in some places
