To me, the one on the left looks like a carton of eggs and the one on the right looks more like fish scales, but perception is very subjective. In fact, since a fish usually swims horizontally rather than up and down the tiles would need to be rotated 90° to be like fish scales ... but that would look rather odd ( *smile* ).
I like both but would depend on where you were putting them. The way they are facing in the the picture on the right reminds me of water (might look good in a bathroom).
It's amazing how we view things. I can see the fish scales which I prefer, but I also see water droplets which make me feel calm and serene. Love organic shapes and these tiles are such a beautiful colour!
For what it's worth, I think the one on the left is more 'uplifting' and the one on the right seems to drag me down. How do they effect you emotionally?
