Hello! 
So, I have recently started doing digital art, but I am not entirely sure what program to use. I have GIMP on my pc right now. However, are there ones that may be easier to use. I would prefer if they were free, but any suggestions would help : )
I highly recommend Ibis Paint X (which can be used both on mobile and PC) it is very beginner friendly and there are many brushes to choose from. It is free but there is a version of the app where you can pay to have access to other features of the app like gradient maps etc.
Procreate is one of the best drawing apps in my opinion but Iβm not sure if itβs recommended for beginners at digital art but feel free to check it out still 
Procreate isnβt free and costs about Β£9/$10.
Thereβs also Clip Studio Paint which is also really good.
But I personally recommend using either Ibis Paint X and/or Procreate 
Thank you so much!! 
No problem and happy birthday
