Too Skinny?

[heyjude]

I got a new beardie about a month ago from PetSmart...I'm not sure how old he is. Maybe a month-2 months? Can you tell me what age he is and if he is too skinny?
I use Reptile carpet substrate. I feed him 10-15 crickets a day (always dusted with calcium and twice a week with vitamin supplement) and collard or mustard greens every two days. Is he too skinny?
Here's some pics.
