Need comments on my ielts task 1

The diagrams illustrate the differences between the library 5 years ago and the one today.

Overall, it can be seen that the number of rooms and studying tables has increased and there have been several changes in the functions of some rooms and areas.

In the middle of the library, four studying tables have been replaced by thirty six individual tables arranged in six groups. The bookshelves at the top of the old plan remain while the desks for student's laptops has taken up the place of the old bookshelves at the bottom.

On the right side of old diagram, the room at the corner now is no longer the library office but the conference room. Next to that, there are extra desks for student's laptops in the place formerly occupied by computer desks. The area on the left side of the plan also witnesses some changes. The classroom has been replaced by a recording studio while the room for borrowing and returning books has been separated into two smaller rooms for each function. The meeting room. however, is still in the old place.
