I hate this mindset kids have nowadays of "oh I NEED to progress" maybe not you specifically, moreso those who are just starting park for their first season before they even learned to properly ski. Just go and ski, when you feel up to it try something new and fun, but no pressure I don't want my parks vibe to be like a gymnastics gym.
*may not pertain to op, I'm just tired of these I need to get better threads.
as far as actual tips go, just repetition until you are comfortable, watch others, what they do, and try to emulate their technique. I think it was the backy during your first season that rubbed me the wrong way.
