you did a great job! great painting!
I've been illustrating and designing with a drawing tablet for more than a decade. When my Wacom broke a few years back, I switched to the MUCH cheaper XP-PEN graphic drawing tablet and haven't looked back. They're only like $50 versus $250+. So at that price point it's a lot easier to try out and see if it's for you.
So much more natural to draw on a tablet and your infinitely faster and more accurate with even simple menu/navigation functions. (I'll still use it just during file management for speed and comfort.) Hope this helps.
