The empty spaces make it look awkward in my opinion, perhaps you could fill them up with something?

It would dull the main figure, sometimes less is more, besides I see this more fitting for an item or a passive.

My main concern is that how the main figure does not fill the space in a good way, but sulking on the bottom right.
You could try to reposition it so the arrowhead is nearer to the corner, just like how you did in your other icons.

It may be a minor issue but I think it do make a difference.
