I need a little motivation and feedback (sorry if too long)

I wasn't going to the gym for almost a year due to work, kids, a hurt shoulder, and other excuses. Started RFL diet on 7/17/17 and went from 188 to about 171 at the end of August. I haven't held strict to a diet but trying to eat fairly clean. I currently weigh 175, but with watching my diet and working out (see below) I can see and feel that I'm still losing fat. I wear a size 36, but am on the last hole in my belt.

Started back to the gym in September just to slowly start stretching everything out again. I'm back to 5-3-1 because it seems the best fit for me efficiency wise. Started on 10/2/17 and did 555,333,531, then 555,333,531. Skipped the first deload week because I felt pretty good and didn't want to stop. Doing a deload week this week with one next week because I will be out of town for Thanksgiving. Here is the current setup for my 531 lifts. Do you see anything that I should add, remove, or replace? Being efficient is on the top of my list. I can be in and out with shower in under 2 hours (includes driving from and back to work as I usually go at about 11 am).

I'm having a crap day because I was so busy at work, just feel worn out and didn't get to go to the gym. I'll pick it back up tomorrow as my first day. I'm 39 and the goal is greater strength, more flexibility and to have a flat stomach (see my abs if possible). Thanks for letting me vent. I enjoy reading all of your success stories.
