The only thing I might say is that while her body in the "After" shot has definition, it lacks in anatomy. Other than that, her expression is certainly adorable in the "After" shot, looking so unsure about this procedure. I also enjoy looking at the relic lines in these sketches to see the effort put into this work.
I made this demo to elaborate on my point. In the demo, her midsection in the "Before" shot lacks anatomy as to the "After" which has anatomy and gives her structure. Everything else, including her fat self, is fine.
