First set of images, I don't even know what I am looking at.
Second set I like the moon on top right and the bottom right.
Third set is too busy for an app logo, especially if it becomes a favicon
Fourth set I'm not too sure of it either.
For me its the second set top right. It's simple enough however there isn't an actual coracle in it but could be viewed as someone looking out into the water from their coracle.
4th set captures the essence of a small boat the best
