Good quality dip powder and essentially all materials?

Pic of my nails; first time ever attempting an ombre type of effect, excited to redo it when time with the trial error I've had. But I've been using Kiara Sky since starting to do dip powder myself (maybe less than a year when I have time to). I think I want some higher quality stuff now, I think I'm ready to take it to 'the next level' of learning and improving, so to speak. Kiara Sky is good! But I see things like activates and curing and I'm curious what yall would recommend. Also any tips generally is appreciated! I didn't do some new methods I picked up on these nails (kids, distracted, tired lol) but I wanna hear thoughts on what I can do/get to improve (: Thanks in advance!
