Good series Tejal,
I also think you've done a good job on the processing, I think this also contributes (significantly) to the three dimensional look.
I find it hard to suggest improvements that are helpful, I can see some minor issues, but also see why you have either not tackled them*, or have had to do it a certain way** - which works (so why change it).
* e.g.
#1 could do with a ccw rotation, but doing so would compromise the composition, with that gentleman on the left becoming far too close to the edge of frame.
** e.g.
#2 had an issue with a tube light in top right corner, which you have dealt with fairly well I think, only a pedant looking for trouble would spot it - cue for Dave
Good White Balance and (on the whole) natural looking colours with good exposures and compositions.
They succeed in giving me a feel for the place.
Well done, Dave
