Her right hand is wrong. That's a hard pose for a hand. I can't do it with mines.

It's a great piece but I feel there is something wrong or missing in this one.

You should edit the shadow. It looks like the light source move with the gun.

Thank you for the advices. I'm not a fan of drawing otters with a lot of whiskers because it oftenly ends with me drawing mustaches or beard. I guess a thread would be my next step.
