These are some of the very first drawings of Alys Brangwin. Her appearance did not change much between this and her final designs. Her vest is the one thing that changed a lot. This version is shorter below the waist and has a smaller collar. Alys also has a bit of a turtleneck on under it here. In the final designs, her neck was exposed with a lower cut. Other than that, she is pretty much exactly the same. Maybe she has a little bit less hair, also.
