wonderful first post.....may there be many more......
i like the angle of the bus to the camera.....although i would like to see it a little higher in the frame.....where it is now, the sky dominates....
speaking of the sky......it's exposed beautifully and i like the rich blue gradient.....the bus, though......is underexposed.... emphasizing the sky even more....you could lighten it in editing.....or next shot, try using a fill flash to balance out the lighting....
thanks again for such a nice first post and welcome to the site.....
peeper
