The figures
For clarity purposes, you must indicate the number of images and also, indicate if there is an image that is based on a revised presentation. That way you clearly lead the reader into the actual descriptive report in the later paragraphs.
and the changes that have been made
This reference makes it appear that physical changes, rather than route changes were made to the city hospital access. That is not the case. There were route designation changes made. Be clear when it comes to information referencing because errors in this part will tend to confuse the reader.
Aside from a few clarity errors, the writer has pretty much explained the differences between the two maps quite well. Word usage could have been better in aid of clarity. The writer shows the potential to deliver a well developed report, provided he learns to use more descriptive words in the correct manner.
