Darwin albino carpet python.

[quackthenoob]

Hi all, this is Louis, he is a Darwin carpet Python, he's just over a year old. I got him as a surprise gift for my birthday last year so I didn't really have the right stuff or knowledge but, I've been doing my best to research and provide a good home for him. he is a happy little snek. from my knowledge he has never been sick, he has no aggression issues, he never acts "strange" he's only ever refused feeding once and, I'm pretty sure it was my fault because I held him that day. (all other feeds I've never held him on the day and he's been fine to eat) with all that said I of course still worry that I'm doing something wrong, from what I've seen of other snakes a couple years older he doesn't seem small for his age but I'm still wondering if he is or not.
I'll stop rambling now but please give me your take for if he seems small for his age or just right.
Thank you!!
