Critique Needed

[meat]

Is the shadow and the white aura on a separate layer? If so make them come in contact with the figure himself, so he doesn't have this grey halo of background color surrounding him. Especially the shadow need to be in contact with his feet, and where it is closest to his point of contact (feet and cane) to the shadow receiving surface (ground), the shadow will be the darkest, then fading out further and further.

You can also add shadow under his coat like you did with his vest.
