I think that it can definitely be improved however I think as my first time doing this it isn't too bad. I could probably improve this by making it have some more complex details such as vents. I made sure to remove any ngon's and made sure that nothing has more than 4 sides.
I also made sure to add bevels which rounds the object so that it is easier to work with.
To improve this work I could make it more simple and not as complex which I will try and attempt another time as I feel like the more simple shapes would be used more.
