#1 is is a great idea for framing the shot. good use of the visual elements. My only wish is that I could see a bit more of the interior. Based on what I am seeing though, that would have requires a tripod, two shots and some photoshoping or negative sandwhiching. #2 Doesn't float my baot (no pun intended. I have seen much more creative work from you, so this just seems to basic. #3 Good stuff! Maybe just enough crop on the bottom to remove the flat horizontal surface in the lower right would help. Somehow that keeps pulling my eye down to that corner.
