Does he look underweight?

Hi everyone I wanted to ask you if my BP looked underweight to you; Last time he weighed 1kg and I use to feed him 4 mices for feeding session.
Here are some photos of him: https://www.instagram.com/bansheethenoodle/

Not underweight as such but he does look to have some retained shed issues you may want to increase the humidity for - or a humid hide/ damp pillowcase just to help him. :)

Yes, already working on it, he only got a small piece under his jaw that is really hard to remove :/

He does not look underweight, you have a very cute collection of pictures, I like the one where he's wrapped around the plushy. :)

Ahah thank you very much :3
