Getting back into AutoCad!

Over the summer I really lost my way with some programs we had learnt last year. So I am recovering my skills in AutoCad and skectup.
Here is my first finished tutorial in copying a cad drawing;

I found an existing cad drawing on the internet.

I imported this into AutoCad and scaled it back up to 1:1 size.
Then i copied over the image, using layers, different line weights and styles.
I then plotted it onto an A3 sheet on a scale 1:300 and opened it in photoshop.
It is in photoshop that rendered the drawing, adding trees, colour and people.

I am really please with my finished image. I think it shows the building off alot more and makes the drawing look more proffesional and interesting.
