Nah what you're seeing is normal. I don't plan on adding sprites for player characters in combat.
It's alright. But it's the first time i play this game and i was confused when i saw the enemies attacking nothing, i thought i had a weird glitch (since i am playing on android and found no image of how the combat should look like) 😅
How about shrinking the portrait images a bit (the ones that show up on the menu, the full body ones) and placing then there? You wouldn't have to make a new sprite from the ground.
An alternative may be the player sprite itself, but i think that one might be too small.
I also noticed that you have some player sprites that are a bit larger... Those could be placed there, the size seems ok to be there.
I'm just throwing suggestions. But if you want to leave it like it is, that's ok too.
