I was surprised by the back darts. They are not common on knit patterns but I did them and they turned out OK. Is probably a nice touch. The side panels on the front are doing the bust shaping and that is a tricky attachment there. mine are not that bad but I think there is still space for improvement and there isn't any indication on how to do it better. I did a muslin 1st and the neck was quite high so I widened the neck all around ( maybe a bit to much !?! ) and added rib on all ends : neck, sleeve, hem.
