Digital art advices?

Been wondering how to make my art feel more painted with little to no line art. I’d love some people to point out things for me.

The two art are my current digital art style at the moment.

Some examples of the style I mentioned are: - Croquette [croquette_crab (Found on Twitter)] - Tasia [tasia.m.s (Found on Insta)] - ELEVEN [0leleven (Found on Insta)]

None of these have pen pressure since I use my iPad majority of the time. I do have a drawing tablet always connected for my pc though. I might just start using that more for the pen pressure. Programs I use are ibisPaint or MediBang.
