I really hope Lisa can do better than what she is doing now. She doesn't look heavy due to her relatively long limbs. While she looks normal compared to other teenagers, she looks overweight to me as skater. This makes her lack of lines and her jumps are not stable as before. Hope she will slim down and come back strong, with better programs.
I really don't think she looks "overweight as a skater." I think it's a question of body type--she is simply a little more curvy than some other girls in skating.
She looks great here: http://www.zimbio.com/photos/Elizaveta+Tuktamysheva/Rostelecom+Cup+ISU+Grand+Prix+Day+1/TWncnbY3lhW
Her body type is perhaps close to someone like Courtney Hicks: http://img.deseretnews.com/images/article/mcontentimage/1211261/1211261.jpg (Please Courtney, ditch those half-over-the-boots tights! You are a lovely girl with gorgeous legs--why spoil the effect?)
Even skaters come in different body types. Thank goodness!
