/ic/ - Artwork/Critique

i just started working to understand simple forms and i ran into an issue when i tried to make a light switch, because the switch seems to be set on a different vanishing point and i was wondering if there is a way to know where the vanishing point should be and if so where i could go to read more into it to better understand how this works. my explanation might have been shit so i used red lines to try and illustrate what im talking about. also sorry if the photo or file size is messed up its my first time posting an image.
