how can I make the drawing on the right look older?

[karmic walrus]

The neck is a bit offset and the jawline is too sharp

I found the character mature (on the design) the overalls are a good idea for a mature character. Add more tattoos could be a good idea idk

The pose of the right arm is really strange and not natural I think u could make the arm/ hand come out a bit more

Smthing like this, depends of what u want after all

(the arm I do is a bit tiny)

And the lower body is weird idk
