I agree the front is perfect, but those are substantial folds at the back, the side view also seems to have a big fold. I also like the shape and length of the leg on you.
I don't have a flat butt, though my mother does. I am going to try Style Arc's Flat Bottom Flo for her in a ponte.
Thank you for the link to the Ann Crowley tutorial. Will try it for my mother.
Perso, I just bought a $20 Craftsy class by Suzy Furrer. IIRC, she had two trouser classes last year. Now, it's 1 class, which incorporates both drafting and design. I will let you know how it takes care of my curves (low wide butt, hourglass, 1m53 height).
