Not bad, but you know what would make it 10x better?
Draw some character sketches such as a man holding a screwdriver fixing a gun in the background or a character posing for the picture baseball bat over the shoulder with a hoodie on? spice it up, the black figures are a bit... unfin.
but i do like the background art it is very eerie.
What about a city in flames? or people barricading a house with zombies coming in the back?
just some ideas lol i'm the idea guy lol full of em.
