Pictures for bathroom

I am thinking about these pictures for my bathroom.  Since my bathroom doesn't have any color on its own so I thought it might make sense to add some color in the pics.
Update...
These over the hand towel rings:

And, this in the toilet room:

Here are the old pics.  I still like them, but I am leaning towards the ones above.
Whelks over tub.  Tide pool in toilet room (actually a little better size than the shell above)
