starting off will just be like a learning process, not quite as extensive and precise like ski racing is, but its fun nonetheless. i don't think switching over will be hard at all, my sister raced her whole life and made the switch over, shes competed in a handful of pipe comps and loved every second of it, now she just skis for the fun of it and coaches little ones. Id imagine for a female such as yourself who has raced their whole life shouldn't have an issue at all. In fact, some of the best ex-ski racers that I know are some of the best park skiers, and just some of the best skiers all over the mtn.
Baby parks and small features are obviously the best ways to get your feet wet, I think. Absolutely no shame in spending an hour or two there to get some stuff dialed, I spent a good amount of time hitting smaller jumps this year just trying to get an air awareness mental block away, and it most certainly helped me. Don't ever get discouraged trying stuff, because that really kills the whole main essence of park skiing, and that is having fun. We all fall, get bruised, frustrated/mad, but letting that get to you just ruins your ski day.
Treat it kinda like racing, you have a bad training run? fuck it, cut your losses, hop back on the chair, and treat your next lap like its a fresh start, you know? (I personally don't know jack shit about how racing is but Id imagine its kinda the same mindsets almost.)
Hope that helps, park skiing is great because you can learn a bunch of cool things and stuff you will eventually carry over to other parts of skiing (I.e, Sending spins off of natural hits, etc)
