Ducky mermaid lineart

Ahaha, art update, as promised earlier.

So this is one of those 'sudden inspirations' you get at 11 o'clock in the evening usually when youre somewhere near your bed. I saw the box of these 'Donald Duck Chocolate Crunchies' I bought at Tokyo Disneyland a few weeks back (Google they were delicious) and thought 'gee, I havent drawn any ducks in ages'. Now, not many of you know this, but Im actually a huge fan of Donald Duck (well, of the comics from artists like Carl Barks, William van Horn and so on, not the crap they fill the magazine with these days) and I might say that my early DD fanarts (which you will never see here, dont worry) were the beginning of my now more frequent and beloved hobby, drawing.

Where does the mermaid tail come from? No idea. It just... came. And because of it I saw a dream of this beautiful college underwater, where mermaids and humans could go to. In the dream, I was a mermaid and my sister (who also was a mermaid) was persuading me to choose this college. Anyway...
The strange long thing shes holding is seaweed, and she just dropped the sea shell which is now hovering under her left arm.

Sorry about the crappy photo quality. I took 3, one was blurry and the other had even more shadows on it
So this is just the lineart, I would colour this if I only had coloured pencils with me 0__0
