The design is really lovely! Some of the wording is a bit awkward, such as the bindoff directions for the armholes and sleeves, and I would have liked to have more detailed measurements in the schematics.
There are currently a couple of mistakes (as of 2/13/11). On the neckline, the right-sided increases are missing. You should do a M1R after knitting the center section. For the sleeves, you’ll end up with a different stitch count at the end than what the pattern says. You end up decreasing by 66 stitches, not just 60 (it is possible I may have misinterpreted the bindoff directions, though).
I did the sleeves a bit differently than directed because I wanted the sleeve cuff to be a little looser (I don’t like anything binding on my upper arm). I cast on 70sts. When it came time to increase, I k16, yo, k2 20 times, k14. This resulted in 90sts. I decreased a total of 62sts over the course of the sleeve, following the decrease directions with just slight modifications, and ending with 28sts. For the last row, I did k3tog 8 times, k4tog, binding off as I went along. This helped gather the sleeve top evenly in preparation for sewing it in.
Beyond that, my mods were minimal. I had to adjust a bit because my row gauge was off. I chose to knit in the round for the sleeves and for the body, up to the armholes. Finally, I did the short rows using a more traditional wrap-and-turn, rather than as directed.
