I think the mirror and pics are deceiving. One week you may look better, one week you may feel you look worse, its up and down. Get a myotape and take measurements. I personally have been doing arms,shoulders,chest,natural waist,navel,widest part of waist,hips,thigh and tracking that. Obviously the waist measurements are the most important to me, and I know I'll lose fat from my hips (just not as much). Any size lost to my arms,shoulders,chest, and thighs aren't necessarily all muscle loss, but should be a lot less than the others.
I've been able to lose basically 1/4 inch on my waist a week, but not consecutively. If I go 2 more days without any loss, I make my adjustments then. This could be a week rest at maintenance, lowering cals, a cardio session or two, etc. Depends on how I feel.
