Squat form check

[RussB]

Coaches, thanks for all the time you spend looking at vids and offering constructive advice.

Male, 32 years old, 5'6", 190 lb. (roughly, no scale to verify, but belt fits similarly to when I weighed 190)

In looking at my 295 lb. squats from last week, I see--
1. Some reps I am losing too much back angle out of the hole--esp. rep 4 of the first set. Chest up harder.
2. Head position starts good, comes up, then shoots back down on each rep. I think it's because I'm looking at the outlet on the wall which is quite close. I need to focus on tucking the chin while looking at it, since I can still look at it while lifting my head.
3. Knees could probably use to move less out of the hole but to me, it's not egregious.

So is there anything to worry about on these or am I right to think my issues are minor? Did I miss anything? This is a rerun of LP for me, so hoping to get to three plates or so before switching to weekly progression. Hit 305 for 3x5 yesterday.

Sets 2 and 3:

Drive your hips UP more, and back less, and keep your chest up a little more.
You're exhaling on the way up, don't.
Fix your head. This is not a what-you're-looking-at-with-your-eyes deal, it's a you're-picking -your-head-up-issue. Keep your HEAD down. The gaze point is for balance, HEAD DOWN is for power.
Your knees are moving out of the hole due the hips going back and not up.

Thanks Steve! Head down/hips up will be my cue.
