I like both styles but prefer your loose watercolour too. What program are you using? You may be a be able to create a happy balance of both watercolour and digital? If Procreate, there is Max Ulichney's Maxpacks Watercolour brush packs (I'm not sure if I'm allowed to post links but search 'Watercolor MaxPack'). If you are using Photoshop and a Creative Cloud subscription the Kyle T. Webster's watercolour brush set is free to download from Adobe. I have used the MaxPack Procreate watercolours and they are very good. I am hardly drawing in Photoshop nowadays so can't really review them but if you already have a CC subscription then they are worth a try. You may already know this but thought I may mention it just in case.
Good luck with everything, your work is so great!
