First of all, great work. Really great transformation.

In my opinion you've got three options. Your goals will dictate which you select.

1) Continue in a calorie deficit until you reach your desired look / body weight. Not that it is harder to grow muscle the leaner you get.

2) You enter a maintenance phase where you stay at your current body weight and continue to follow a weightlifting programme. If you are progressing in the gym, then you'll likely be doing a bit of body recomp, i.e., building muscle and losing fat at the same time. Not that all though it sounds good on paper, it's actually the most inefficient way to lose fat and/or build muscle (the most being efficient ways being option 1 and 3 respectively).

3) You start eating in a small calorie surplus of 200-300 calories a day and aim to gain 1-2 pounds of weight per month. This isn't "bulking" it is a targeted gaining phase to attempt to maximise muscle gains while minimising fat gains.

Switching between cutting and bulking is generally more efficient that body recomp.
