Thanks for the comments vag!
Yeah after looking at the videos I have to say the way I squat now is the best way. It's not like the knees aren't going forward... they are quite a bit. So the quads do work here too.
In the deadlift I stay with the hips high and load the posterior chain, and then try to lower them a bit while at the same time starting to lift (knees go a bit forward, there is some quad load as well at that point).
Obviously the form will suck from a point on, although with 160 kg it doesn't look THAT terrible (there is some back bending but I expected to look much worse).
In the clean... it's just a terrible thing with the lack of the rack position... I either catch it on my chest in a very high position or I fail the lift. At least I can use lighter weights and maybe benefit from the more specific speed of the lift to the jump...
In the snatch, the more I went up in weight the more I turned my hands inside.
Check this video for what I mean:

Before doing that I had the tendency to throw the bar forward (because that feels more natural, like in a KB swing, where you keep the arms straight all the way). But when I did this it was easier to keep the bar close to the body.
For the calf raises, that ROM is definitely VERY shallow. That's why I filmed it in the first place - to see how bad it is. After that I did sets with 70 kg and full, complete ROM. It's still very difficult because you have to maintain the balance.
