I have created a simple character, but it looks bland and empty, how can i improove it.

I have made a simple character in blender (and painted some details over it) with intent of blocking it out so I can 3D model it later. But it just looks a bit boring tbf, any tips on how to improove it. I havent modelled small details like belt buckles and wires, but the larger stuff is already put down. What else could I add (apart from shoes xd)
