Those characters were designed really well! I love them! They'd fit perfectly into the game. The food, my honest opinion that they look awesome, but haven't got much of a Stardew "feel" you know? Still look super cool though
I agree with squid they do look kinda off Stardew valley a bit but that doesn´t make them worse. Would be really cool if you did something appropriate to the Stardew theme (Well you know with the design of the character the style you did it in was cool) .
