Hello. I wish to raise a query. Let's make an instance first:

Jimmy is sending Mary a song, and the progress bar is still in the middle. Jimmy wishes to hear Mary's reply of her impression towards the song, so which one would be apt to say:

1. Please let me know your impression after you have listened to it. (I have been using this all the time, but I realize that I may actually be wrong since present perfect tense is not meant to be used to describe the future event. Nonetheless, the reason that I thought it was correct was because I would place myself in the future point on the timeline where the action of listening to music has been done already. It's like looking back from the future, so I always applied the present perfect tense in this sort of request.)

2. Please let me know your impression after listening to it. (I believe that this is correct because noun is always one of the proper choices after a preposition, like "after" in this case. However, what should I do if I want to include an object in this sentence?)

3. Please let me know your impression after you finish listening to it.

Please kindly tell me which expression is correct, and if it is possible, please also add some explanation to aid my understanding.

Thank you very much!!

Endeavour1. Please let me know your impression after you have listened to it.
2. Please let me know your impression after listening to it.
3. Please let me know your impression after you finish listening to it.
All three are correct. In terms of style I find the first the best and the last the worst. You can also use: Please let me know your impression after you listen to it.
EndeavourI realize that I may actually be wrong since present perfect tense is not meant to be used to describe the future event.
In a subordinate clause of time, the present and the present perfect are both used to describe a future event. The future tense itself is, in fact, wrong in that context.
Endeavourwhat should I do if I want to include an object in this sentence?
I don't understand the question. ... after seeing the photo.

Hi

You used the Present Perfect correctly in the first sentence. You should check the rules of the time clauses to understand why. This has already been discussed on this forum, you can read very good and long explanations here:
