On top of what Night Fox said, that wheel in the top right looks odd, it's shape is off for the angle, looks more like an oval wheel than circular like the others. Other than that it's fine.
From the angle the car is at, all of the wheels look appropriate. I don't know where you get that from.
i made this as a complete joke
can i see some of your real art?
i'm kind of going down Char's line of art except i'm experimenting in animal drawings and portraits insteadhere is a walrus i drew with pencil, paper and colouring pencils
