dancing: their dance line is gaeul, wonyoung, and yujin. the fact that yujin and wonyoung with their average dancing are there should already tell you how weak their dance line is. gaeul has never even stood out despite being the main dancer and her dancing is just mediocre. people criticize karina as an average dancer but i think karina is better than gaeul. i think starship should have either pushed gaeul to become a better dancer or invested in another trainee. they should have tried to recruit chaeyeon or something.
singing: all of them are in the vocal line minus gaeul so ill just assess the main and lead vocalist. liz is a good vocalist but not good enough to be main. literally any other 4th gen group's main vocalist would eat her up. yujin is a good vocalist to and good enough to be lead but i def think that liz is also lead vocalist material. starship should have really invested in getting a vocal that would give ive the oomph they need.
rapping: their rap line is rei and gaeul. rei is good (the rap she wrote was good) but gaeul is... really average. im honestly not sure why she's even in the group. she really doesnt bring anything.
overall, their strongest line is their rap line not because rei is so good but because their singing and dancing line is so weak. rei is alright but i think she's just equal to some of the other 4th gg rap lines (itzy, nmixx, purple kiss, lightsum) or worse than (gidle, aespa). talentwise, ive is honestly very underwhelming.
