hmm...i think you may be wearing it backwards only because the pattern has the straps in the front much longer than the back, making the front lower. but it looks great no matter how you wear it! great job!
Here's the To Dye For sweater I knit up last winter. It was my first garmet ever. Now that I'm looking at it I wish that I had of used smaller needles around the shoulders because the Rowan Polar yarn stretched a bit. The sleeves were too long too but I rolled them and them blocked them up. Also I didn't know how to do necklines at the time so that got pretty out of control. But I'm still quite happy with my first sweater.
And here is the beginning of Tank Girl for my sister and the finished back. The front will have longer straps and a lower neckline.
