We could work on a little roughness and metalness maps! like more details to the dirt of tire, more scratch to the body of the car, but at least you got the blockouts done! Keep it up!
cool animation. one thing sticking out to me is that the tread on the tires seems reversed? Should that v point dig into the mud for better traction? Maybe it doesnt have to but I think it might look more aggresive like that. Anyway pretty cool model
There are lots of technical things we could mention but you've made a little truck and it looks like a truck so you made a good start. I think you should learn to apply UV mapping and paint some nice textures for it next - that covers the basic requirements
