Here's some things I noticed:
-Your choice of music was bad.
-You edited only the beginning of the video
-You used uninspired and unrealistic camera positions.
-The movie was too long
If it was only to show your driving abilities :
-The car used was too slow and too easy to handle: I suggest one of the LXs if you want to showcase raw talent
-You should use a smaller autocross track instead of your long layout that is pretty similar to the ones you find on cruise servers.
Keep practicing and you will only get better!
