The ‘slant’ of the pick is irrelevant, it’s just a function of grip. Pickslanting is really a type of picking motion that goes into and out of the strings in a linear fashion. It is different than the curved movement you are doing here. So I would try not to think about ‘pickslanting’ as being a thing you can do while doing this, since by definition they are different movements.
However wrist crosspicking requires a tilted forearm with respect to the strings, either pronated or supinated. And the movement will actually be different based on this. If your forearm is parallel to the strings with no tilt, then wrist crosspicking is not possible, only stringhopping or wrist-forearm blends.
In your case you are using the supinated deviation wrist crosspicking movement. And you are doing it correctly so there is no need to change anything. If you play around with the grip you could make the pick look ‘slanted’. But that won’t change the movement unless you… change the arm orientation and/or deliberately change the movement. And then you might not be doing the same thing any more.
Again looks great do exactly what you are doing in this clip no changes and make it habitual.
Congrats on the baby!!!
