I don't really see any rounding, but it's likely that you'll have some if you go deeper (which you need to do as well). Widen your stance and do some flexibility and mobility work. You can also focus on sitting back into the squat, and that should fix some of your forward knee travel.
Front Squat:
Depth and staying more upright.
Other than those, you're better off than a lot of vids I've seen. Get to work!
cheers mate, I have lost a lot of my flexiability over the last few months so am working on some stretching before and after my workouts to get it back a bit.
