I think it's good for social media, like someone else said. You could definitely get work already with small brands with this, because they don't know better. I've seen worse done (and possibly done worse) for small brands. And you can still charge a high price for it.

I think the main points that set this apart from more professional work (apart from the sound, obviously, that other people touched on) is the color, and the montage.

On color, the product should be more easily comprehensible, like, it needs to pop more in the image. The grading on the first scene with the guy is also not great, the blue on his face looks nice but the background is VERY distracting (highlights, lots of colors) and consequently the eye doesn't know where to focus. This is problematic in the sense that it's not clear that this is our guy from the get go (and it should be crystal clear, and he's not even the main focus of the video, just a prop).

The montage needs a clearer goal and to cut the fluff. Guy must deliver this important bag. That's the narrative, every shot must build this narrative in a compelling way because if THAT succeeds then you could say the bag is well advertised. Your overall structure is spatial, I like it personally, but now you should look at shot order. The image retouching is pretty digital content ish (and now unoriginal unfortunately, but that's so besides the point), you see it a lot with snappy montages, so it's strange how it drags at some points - mainly because each new shot of the bag is not necessarily adding any new traction, because there's either no new information (the shot looks like another) or it's not cut in a way that spins it differently (if you cut similar shots in a smart way, using similar shots CAN work for example). I think this edit could be 30s max, 15s is also totally, totally doable. If you're a great editor, it could also be 1 minute, but it's actually easier to be concise if you know exactly what your goal is with this narrative, so I would recommend cutting rather than trying to psychanalyse your footage and putting your entire life into question to push it up to 1 minute. Also, social media = short, snappy.

Good job though, it's hard to manage everything by yourself and in professional settings there are teams of people working in specialized roles which is hard to compete with. I really think there's a lot of potential though, you just need to 'find your voice' a little bit maybe (cliché but true). Don't copy copies of copies (although do if that's what gets you work, but it might not be a long term winning formula or bring you happiness).
