Shell-ing a-Round #15 and #16 - Nautilus

Yep, I managed again to loose quite a few days! Many things came in the way, and only today I had the time to work again on the shell series. The good news is that I finished two of them, so maybe it is not too late to catch up...
Both are acrylics, ACEO size. This time the underwater versions of Nautilus.

Shell-ing a-Round #14

Another nautilus shell on the beach. ACEO size and acrylics on paper, as for all shells so far.

Shell-ing a-Round #13 - Nautilus

Next shell in my series is Nautilus - lots of stories about it, and its chambers and all the math with Fibonacci series, as you probably know. I do like it very much, because of the beautiful stripes it has on the shell and its rather strange "look" when alive. I started with just the shells in the sea water, on the beach, again ACEOs. First one today, and the second tomorrow.
