Guard Ominous

A guard at their post with a hand ominously reaching towards them.
The initial sketch is a crop from a hand drawing practise session where I got a bit bored and drew a character.
Sketch was done in pencil and then inked, with colour added digitally using Corel PaintShop Pro 2022.

I guess I should have done the hand, but maybe it represents an invisible nature of it. Or maybe this is what the guard is imagining is happening due to paranoia.
