Improve Minecraft Skin?

Hi. Attached is a picture of my self-modeled Minecraft skin.

Now I wanted to ask what I could improve because I'm not yet satisfied.

A second layer already exists, but I'm quite happy with it. This does not change anything on the hairstyle or the pants, e.g. Only the shoes are different there.

I would remove the red on the head and make it beige.

The dark on the body could also get darker.

I think the red is too strong

I would make another pattern (e.g. A brand) on the top.
