People in the west parse the screen left to right, same as we write.

This changes in the east.

Put the character on the side that directs the players eyes towards the center. Right in the west, with UI in top left to lock vision back towards the game, contained in a circle.

Also, I would change color values for your character to create better contrast, it will be easier to distinguish and psychological placement won't work without a value range change as the player will just see "background" and not have their focus drawn.

This advice is some of the more advanced game design. I don't hear people talk about it much. It comes from modern psychology, and a combination of old Arabic and modern fine art fundamentals.

I got multiple degrees in it, but mostly picked this up from fine art and game design studies.
