i dunno how to use photoshop either friend!! so i can’t help with that unfortunately :^ ( i use SAI and Sketchbook Pro which are way easier..but drawing on a tablet is something that can take a lot of getting used to because of the disconnect between where you’re physically making your strokes and your computer screen unless you have a really fancy cool tablet where you can just draw on your screen hm!! i would try practicing smaller things like i dunno maybe just doodle a little bit until you start getting the feel for your tablet, instead of trying to produce a big serious picture i guess??
