Hi, thanks for applying.
I see a few things to point out in the app itself:
Their subspecies, age, religion, and whether or not they're a listener or receiver are not mentioned.
7.0 for a chemist on the Horizon is too high, and this is more apparent when we consider that their views on Glorsh are known to the Federation. Without going to rehabilitation or genuinely changing their views on Glorsh, there would be no way that they could maintain Primary status. While on the topic of SCS, the frequent moving between Primary and Secondary is not common. Social mobility is (debatably) achievable in Federation society, but moving between the bands like how you describe would not be normal.
Their colouration would not change entirely through diet. While noticeable changes can occur, major changes to overall colour are mostly observable in the abdomen or markings like spots and stripes.
There is no real mention of events within the Federation impacting your character. While the Federation has not been involved in wider events, Qu'lil would not have been completely insulated from the recent events involving the Traverse or the secondary effects of the phoron scarcity.
I'd like you to address this feedback before I can ask any questions related to the character's backstory.
