It seems there is a cast shadow on the sand bellow the mirror of the entrance side. It stands a bit in the way of seeing the whole silhouette of the bus. I would delete or lighten it And about the tires - they are ok, as you showed motion blur only on that part of the bus where the back most wheel is.
on the rear end there are 2 wheels. and in front of them there are 2 on each side.. so total of 6 wheels.. 4 of these (which don't turn) are connected to the electric engine.. and there's not enough room for them to turn..
