I think it helps me line up my art and see where I should put parts of my art :>. I don’t know why, but when I draw on paper with grids or lines my art looks better than on paper without a grid. Just some suggestions for things to add to Sketchbook are an option to have a grid on the canvas to help you line things up (if this is already a feature and I just can’t find it then sorry, I'm being dumb). All I know is that different artists have different styles and like different art apps (if they use art apps), so look around and find an app that works for you! Just keep trying and you’ll find what works best for you :>. I’m not really sure the reason I like Sketchbook so much, it might be because it has a nice loose/free feel like the way I draw. I really like Sketchbook and I use it a lot for my art. I have used lots of art apps but this one is my ultimate favorite :>.
