Regarding music choice.
Here is some reception/opinion from her Chinese fans.
Chinese fans are not particularly excited or in love with her music choice this year. Some used the word too loud/noisy
Eunsoo among many promising young girl skaters is surprisingly (maybe not that surprising) quite adored by Chinese figure skating fans, due to her familiar asian beauty look and beautiful body type (loooong legs especially), and her resemblance in terms of physique (and jumps to certain extend) to Yuna Queen.
So here is some common opinions regarding her programs and possible music choice for next season
her Chinese fans wish she can try some lyrical music for a change, something like Yuna's lark ascending. to really use those lively long lines.
It is great that eunsoo is challenge something different from normal generic lyrical, pretty music for young girl skaters.
but it is kinda repetitive for her own range of style. Also, lyrical music will force her to polish her skating skills (which is an area she needs to improve) and to learn certain type of lyrical moves that will help her to improve her posture and extension (more than one people has mentioned, her posture needs somewhat improvement, but I personally did not see it, cos she does has a very beautiful and squared shoulder and just look down habitually a bit).
I personally think 2 contrasting programs in terms of style every season would be ideal, plus a third lovely EX.
Also in terms of techqiue
her -3t in her combo jump although has great height( even higher than first jump, which is a beauty) needs to be improved, she has a bit bended toe picking there, maybe should watch Yuna Queen's -3T and learn from there.
