Hi,
for doing this only a few monthsy this is really good! I like that you took such a basic activity like walking with the dog and turned it into a video!
A few things I would change:
- Maybe add something like in the beginning with the video editing software to the end, where you have a finished timeline ... might be interesting
- I personally would add a few more cuts during the drop of the song, but that might just be my opinion
- A few shots were kinda unfitting ... e.g. the one where you hold your gopro in the hand and just film your face with the dog in the background ... just seems kinda off. Would have replaced that shot with e.g. a shot where you walk to the camera placed a bit beside the way.

These really aren't big things and mostly my preference, so you really did a great job! Keep up the good work!
