Fiat 500 Model

Would like some critique, mainly focused on just the model itself and what I can improve, I know there are some missed details. Is my edge flow crap? How can I improve it? The back of the vehicle seems a bit off to me but I’m not sure how to fix it without screwing my topology up. Also where different pieces come together I have trouble.

This is my first car model so I think it came out alright.

This was made following a pretty loose tutorial: https://www.3dtotal.com/tutorial/1756-modeling-and-texturing-a-classic-fiat-500-blender-gimp-by-filippo-veniero-vehicle-car

Not bad for a first model. Now I know that isn’t critique, and doesn’t help you with much, but frankly I’m only replying to this to raise the thread in the hope that someone who does model can give their advice.
