You're only as good as the tools you use. They are improving fast though, you can already see a noticeable difference between the artwork in Volume 1 and Volume 2, and they were made about six months apart.
I'm pretty sure a pro is much better with amateur tools than a newb is with elite tools.
Give me the most expensive and fine art brushes and I doubt I could make anything worthy of hanging on a fridge. Bob Ross could outclass me with a napkin.
