I really liked the 2nd shot. It is a very nice example of creatively and successfully breaking a "photography rule." Vertical lines coming straight up the middle of a composition are usually frowned upon, but I think in this photo the line really works well to draw you into the picture.
The first frame is something I have NEVER seen before. I love the chair theme. Thought provoking to say the least. Technically I would try a bit more contrast as well.
