3D ichthyosaur

Here I intended to rough in an ichthyosaur and then drag the lines around, but I guess I only know how to drag around pen lines. I was petulant because Dad wouldn't explain to me how to get to the drawing tools so I just liquefied the background as well as the sketch. The background is meant to be 3D for pen and paper doodles and I found it while looking for interesting graph paper from printable paper to track my New Years' resolution progress. They have hexagons, percentages, everything cool but so far I have only used the 1/4 inch square grid.
