So let me be the first then:
[Just as a preface: Everything of the following is based on the image of Cherish I've formed in my mind based on your description and the posted PC, it might not really mesh with what you had in mind.]
Judging from the PC, Cherish first priority is to be a first-class mechwarrior, second to none, using this to propel her ahead. Her ego seems to match this ("greatest warrior"). She is rather impulsive and has a good-sized streak of stubborness.
Basing on her description, an Acrobatics skill of at least 1 might be useful, as she seems to be the most fit our whole bunch. (Acrobatics covers, among other, tumbling, jumping and evading.) Another skill you might want to take a level or two in could be Survival to cover those times in the wild (referring to her pets and the material of her flute). [Also comfirming her general attitude of perseverance.]
On the other hand, given her omewhat hot-headed and impatient approach to things, perhaps it would be fitting to reduce Tactics a bit and improve Leadership instead. (Her 'leading-by-example' style should mesh well with most Clan Warriors' attitudes.)
Tying into this aspect, perhaps you should consider to get rid of the level of Negotiation. Cherish doesn't strike me as someone who bides her time and tries to goad her opponent into a bad bid, I rather see her in the vein of the Black Widow ("Give me your best bid, no matter what, and I'll rip it (and you) into shreds!") Given her "flaws" she might even overextend herself just to win the bid and fight, relying on her own formidable abilities to pull a victory through.
So a level in Blade could be in order, just to cover her bases in case her opponent gets some strange ideas. Also fitting might be a Special interest: Clan Jade Falcon as she seems to have tangled with them quite a bit. (After all, they did merit a tattoo.

)
[BTW, to me Cherish seems to be a fitting candidate for an EI implant.]
