You're a good newb, I like you already. You do have a few things to work on, so I'll give a few "big" ones to start with.
1) Keep your eyes (and head) down in the same position throughout the rep (i.e., don't lift your head up as you ascend). Pick a point on the floor 4-6 feet in front of you and stare at it. Don't look away. Put an actual object there if you need something to focus on.
2) Your first movement as you descend appears to be breaking at the knees first and sending them forward. Were I coaching you in person, I'd cue you break at the hips/sit back earlier.
3) Partially as a consequence of your not doing #1, you are lifting your chest a lot on the descent, rather than using your hips to drive out of the bottom. Instead, think about "pointing your nipples at the floor" and driving up hard with your ass, and then stand up straight at the top.
Using the TUBOW for now is a good idea too.
