@Dewndeym Every time I see screenshots from the pokemon games, the thing that always stands out to me is how I usually only see the same exact tree model.
My old work consisted of a bunch of shapes I'd draw and layer together with the pen tool and clipping masks. The uniform look of the lines was both a benefit and a drawback, but I could adjust my lines after the fact which is why I did it for about 4 or 5 years
