In regards to what you said here "it’s not entirely done but its good enough",
Don't stop until its the best you can do. If you're trying to impress employers, 'good enough' just isn't good enough. I find in contradictory to say that you're trying to boost your potential, you're trying to get better, yet you stop when you think the design is 'good enough'.
As far as a critique on the design goes, I think it needs more detail. The structure and idea is pretty good, but I think you should spend more time on it. Sure you spent a week on it, but it only adds up to a few hours. If you really want to impress employers, you need to spend as much time as you can working on your designs, making them the best they can possibly be.
