You may be carrying it too low. I'd also bring your heels together by about an inch.
You are not going to want to hear this, but you should do what you can to find a better place to train. An unstable wooden rack, a standard bar, uneven ground, and squat sessions that get cancelled by rain storms add up to decreased safety and less than ideal training conditions. I'd like to see you squatting in some weightlifting shoes on a flat concrete slab floor with a proper bar and rack and, yes, using a belt if you feel like it might be time for one. Some of your form issues will clean up by eliminating these variables. Depending on where you are in Croatia, you may not have easy access to these things. Do the best you can.
