You know, I noticed that that dismemberment prop is not so bad, you just need to apply proper texture and it will look pretty good.

If you want to try, you can use texture I provided. It needs a bit more improvements which I do later, but so far it is better than nothing.


Your posing seems to be fine, maybe you need some experimenting on more realistic expressions and add some backgrounds( at least render with plain HDRI) and it will be a complete picture.

Anyway, you could already start doing more interesting pictures like fight scenes or something to show a story. Your skills are totally sufficient for that.
