Entry #2: I like the overall feel apart from the sharp angles of the tick in the middle of the blue ripples. A drop might work better if it isn't too cliched...I would leave that to your judgement. I like the colour used in 'Rainmaker Perpetual', I also like the fact that it is easy to read. I do feel you could make the feel even more exclusive and perhaps a fraction more serious.
Entry # 3: Same comment regarding the colour and font. I like the colour of the motif but not the design. the sharp strikes don't give the feeling I'm looking for.
