Becky is looking very pretty there. Great work on her clothing especially. That's a lot of detail you put in there. Her top must be extra tight to outline her abdominal area so visibly through both layers. Sexy hips and overall curves, to go with the clothes. I was going to say her neck is slightly too long but actually I think it is her head that is slightly too small. Enlarging her head by 5-15% may fit her body better.
