Thanks for the extra info. I quite like the color scheme, quite subtle and balanced. I guess you know that there are some roads that are not connected? This shouldn't be to hard to fix in illustrator though.
Some things that I think need some work are these:
1. The point of the map is to show the locations of the hospitals in Paris, but the use of symbols makes it difficult to locate exactly in which street they are, where the entrance is, etc. Maybe you could use the contour of the buildings and make these blue? I think this might make them stand out more.
2. The placement of the typography could be improved. I think it would be better to place the names of roads on the roads themselves instead of next to them. Probably it's better to use a slightly bold sans serif typeface (say Arial Bold). The use of all caps might also help. For the names of the hospitals it might be better not to use a text box and make the type itself blue.
Just try some versions, see what you like and don't like, then post 'm again!
Hope this helps,

Hi Jeffrey,
Your right, I will consider for your suggestions and make some improvements.
I know about there are some street not connected, I'am still editing. And for suggestion about contour building, may be I must work more patient to create them

.
Thank's for all your suggestion.
