I like the beautiful background (better than what I can do) but if you were trying to make the bike look like it was moving along the dusty road, you didn’t do a great job at it. I don’t really have any advice besides just observing videos of how bikes move. I don’t know actually but I have been observing the things I’ve been animating recently so that might help.

I believe this is pretty well drawn and the perspective is quite nice. The background and foreground are absolutely gorgeous but my score is low because there is not much going on here. This is probably a test but it would work better as a gif.

If you want advice on animation then I would say that if you want this thing to look like is moving then loose objects should be moving like the tools inside of the box, those belt like things holding the box and the person's clothing. Ofcourse adding a spiral effect to the wheels will also make it look good when moving and because of the dirt road some sort of dust cloud behind the wheels would be a pretty nice touch.
