For me, a few things.
First, the colours should be more punchy, the whole image looks washed out and lacking in contrast. You can fix this in processing.
Second, I'd prefer the man heading towards the camera rather than away, and eye contact would be great.
Third, I'm not a big fan of logos on pictures, but this is neither contrasting to stand out, nor subtle enough to not take your attention away from the subject.
There's a lot of plastic reflections too, but you can't do too much about that, apart from change position. Good try, but engaging with subjects like this will give better results. They usually have good faces for portraiture too, having spent a lot of time outdoors.

Hi Sonu, perhaps you were a little scared to face this guy head on but asking very often gets positive results, otherwise, try from the hip allowing plenty of space to crop your pic later.
I say that because you really have to take this kind of picture head on with the sellers face in view. the time to do otherwise is perhaps,whena sale is being either bartered or underway when capturing both parties can be fruitful. Looking at the composition generally, your seller, looking out of your picture would look far better on the LHS and looking into it.
EXIF wise I would also use a snmaller aperture to get a better DoF maybe maximum f9 and perhaps f11. Then as nick says, do a little bit more work on your processing, and perhaps less in uploading such logos which prove to be worthless anyway. I mean - what is "The Gallery"?
keep at it and the results will come.
