I honestly really like drawing in perspective like this, but the tutorials and directions on how to block up the proportions and such are confusing as F**K and too much work so i do not adhere to that because i am LAZY
the only principle i follow is that the farther away it is the smaller it gets bc honestly as long as you can draw an arm in general, you can blame whatever looks weird on the perspective, and usually no one can even tell if it is unproportionate
