Laptop sleeve/bag

I wanted to give a laptop sleeve/bag to my brother and have been working on it for the past few days and finally it is done.

I am not really satisfied with the way it turned out, but then this is my first attempt, and learnt a lot during the process. :)

Again, I did not use any pattern. I just measured my bro's laptop (17" diagonal screen) which was pretty big, and the picture tells how it finally turned out.
