The Hoth base looks quite on brand for a meld of SW with AD&D, well done. The color is an excellent addition.

I always turn my layer off and on again to check before I start due to having messed up layers severely before. It's a habit you'll definitely notice in my screen recordings, every once in a while I'll pause and double check it's the right layer by toggling it on and off.

Brushes depend on what program you're in.
