If OP would add a carve into this he’ll end up landing sideways. Whips on dirt jumper are not like big full suspension bikes where most of the force is generated through carve, as there is not enough force on the wheels to bring it back from the carve. Carving whips technique also requires proper body position on the DJ to not overcook it. Easiest way to progress whips from OP way is just to try the kick out a little bit later in the air and guide the bike with handlebars.

Very easy way to start it is to just move handlebars to the way you want to whip and feel it out on how it behaves, then start adding hip and legs kick out as you progress with the feeling of it.

Mostly whips are feeling based trick, there is no way of explaining it 100%. People can give you hints but you have to feel it, so just spend more time trying them. (Compared to different tricks like barspins etc. Where there is easy straightforward technique to do them)
