Giving directions

I was practising my English, I needed to give directions to someone in Bogota. I would like it if you could help me with any corrections.
Can you give me a number between 0 and 10 for the work I have submitted.

Thanks

The person is on the star and needs to go to the museum.
As you go out the door make a left and walk up calle 13 for two blocks, turn right on "carrera 4" and walk for one block, at "calle 14" turn left and walk for two more blocks, then turn right and go straight a head up "calle 16" for just 1 block then finally turn left on the corner and you will see the museum on the left in front of the park.

Well done with this entry. I would give you a mark of 7 out of 10.
