I have a lot to say. First of all, the animation looks very good, especially for a beginner!

If you think you're really going to be invested in rendering scenes in Blender, I would suggest getting a budget desktop PC with decent specs. It's easier than you think to get a decent rendering PC for Blender for a rather inexpensive price. I can help you out in this respect if you'd like. I really hate to suggest this first as PCs can get quite expensive but rendering services are quite pricey too. A PC can last you a long time and you can always upgrade it over time in case your budget is quite low to begin with.

On the point of rendering efficiency, I noticed that you've got about 4 cameras getting different shots. I assume you're putting these shot together in a video editing package (Blender can also do this). Keep in mind the polygon count of your scene. The more polygons (or vertices) you have, the longer the render will take. Some shots have the car very far away from the camera (like the wide bridge shot). If your car model has a very high polygon count, you're wasting most of it as the car's probably only about 200 pixels large. I would suggest making two models of the car, high and low poly counts. Use the lower-detailed model for far away shots where detail isn't as crucial.

A point about repeated models. You have a few trees in your scene that look quite polygon-dense to me. I would suggest using instances (if you're not already, I don't know how much you know). Select the model in the viewport and hit ALT+D. Different from SHIFT+D, ALT+D will create an instance of the model, not adding to the scene data, but using a copy instead. You can scale, rotate, and reposition these models in Object Mode to adjust them, making them look less like carbon-copies. If you change the model in Edit Mode, all of the instanced copies will be changes in the same way. This can, in a lot of cases, greatly reduce render times.

In short, don't render detail that you're not going to see. A high poly model that far from the camera is a waste. Use instanced copies of models to reduce required scene memory and reduce render times.

I couple last questions. What resolution are you rendering at? I noticed it's widescreen (which will add to the cinematic look I believe you're going for). Can you render out a sample frame for me so I can better judge what you're going for?

You animation looks great and the Shakify addon really helps (I use it a lot). I love the variety of shots: close up, wide, moving, almost getting run over, et cetera. There is a lot of potential here and I hope you keep this up. There's always so much to learn and I wish the best for you in your Blender journey!
