Martin the warrior vibes

Are these AI? I only ask because there is no artist credit and this and the snail one both have a very uniform style. I hope not, I do like them and would like to share.

Are these your own pictures OP or from somewhere else? they're great all the same!

I keep on going out of pure spite. As long as there are people alive whose death will bring me great joy I will persevere. Also I have to finish reading One Piece.

Why is it a mouse? I am not a mouse. Are you telling mice to keep feasting on our grain supply? What is this, what side is this guy even on? I do not live in medieval times. Also do NOT stick your sword into the ground like that are you completely daft? It will dull the edge and blade and it will get your scabbard dirty and possibly bring rocks in with it that could get lodged and then you couldn't pull the sword when you needed it.

Also seems kind of a waste of time standing on a battlefield that has clearly been abandoned for decades seeing how there's perfectly weathered skulls laying around on the ground.

"I must keep going", with what? Pillaging the countryside, as it seems you are doing in a burning swamp?

Is there a higher res version of this?

Edit: for anybody interested, there is an Etsy shop with this print.
