looks better now!
just the metal part is still flat.
since you can not add depth to the cutting edge
you should just try to make the metal left and right of
the handle a little thicker, it looks flat there.
This comes from the coloring of the depth.
While your fullscreen image, show's clearly that it
is a three dimensional object, you can not see this
in the 64x64 solution. You should make the darkgrey
line (left and right of the handle) much darker or
bigger. I think this is why the axe looks so flat and 2d
in the button.
If you can make it look less flat, I'll use it in the Inferia ORPG.
