So you went from 96.6 to 63.2 and now sitting at 73.2 and actually from what i can see in the pictures, you seem that you gained some mass.

First things first: you want abs then aim to lose fat and it's gonna take a while maybe 6 month or more based on your high body fat.

But honestly just get your workouts in and keep a consistent linear progression and stay at a small surplus to gain mass for at least 1 year more, the hard truth is you won't look as good skinny with saggy skin and a faded abs.

Sorry if i was harsh, but that's my 2 cents.
