The shadow is still using the on-the-table perspective. Also it feels a
little different than other axonometric icons. Perhaps comparison with
some cube-like icon would help to better it.

Also, please use linear gradient for the fill with brighter spots at
top, the radial gradient with dark spot at top does feel strange.
