Help/opinions needed

I was asked to sex this adult Mali uromastyx. I am leaning one way but could really go with either sex. So I was wondering what other people might think.

Please only guess if you actually know what to look for to sex a uro.

Thanks for any opinions

You would need a clearer picture of the tail. Lift the tail vertically and take a pic from behind.
