Hey Gani, looks like a female to me. It can be kind of tough to tell when they're young. Up until last month I thought I had 1 male and 3 females, but actually 2 are males and 2 are females. The large male was pretty obvious, but with the small one, I was only able to tell after I put him in his own tank.
Those pantos look nice and so does your istlanum.
