Huzaifa AsifGetting to see a good picture of yours in long time.
Does it sound fine? No it doesn't and the meaning is not clear.
Try to write a better sentence; start with a clear subject..

Perhaps you mean something like

I finally get to see a good picture of you in a long time.

IvanhrI finally get to see a good picture of you in a long time.

The underlined part is not good in that sentence.
The question is whether this is the first good picture I saw or will see.

I actually mean to say that I am seeing a good picture of you after a really long time. You look photogenic in it and the background is quite alluring. Thus, it's a good picture and it's long since I have seen such picture of you.

Then you want It has been a long time since I have seen such a good picture of you. If you ask me, this is an unusual and a potentially rude thing to say. You could just tell the listener that you like the picture.

Oh right but I have seen people say, at times; We haven't talked to each other in long time.

Perhaps this isn't the correct form and instead we should say, It's been long since we have last talked.
?

Huzaifa AsifOh, right, but I have seen people say at times We haven't talked to each other in long time.
Perhaps this isn't the correct form

No, it’s fine.

In this case both are considered correct but in that PHOTO's case, you are not considering the sentence what I wrote in the first place correct?

Huzaifa Asifwhat I wrote in the first place

Are you referring to "getting to see a good picture of yours in long time"? This is wrong.

Okay.
What does 'get to' refer in any sentence? Like, "How do you get to play so well"
and there are several examples that often baffle me. Thank you in advance..
