TSR card game [Postponed]

[Hoeloe]

The head is just plain not smooth. At the top left, because you go into a straight line of pixels for a while, it removes the illusion of a consistent curve. At the top right, your curve is slightly too steep, making it look like there's a slight bulge. At the bottom right, you have both of those issues combined. The base is like it's trying to be a straight line and curved at the same time, making it look very wobbly. Make it a consist faint curve, like a squashed U shape.
