Mendacium Family Adoption

Hi! Hoping I could grab an adopt as my first character :)

Name: Larisa Mendacium
Family Relation: Aunt
Gender: Female
Height: 36"
Build: Light
Appearance: I'm trying to figure out how to fit her in with her offspring's appearances, but to do so with my single 400 gem store purchase...so I don't think I can use any of your suggested designs.... Black base coat + varying shades of grey over shoulders/dorsum + age-related greying of muzzle/ears/ventrum/paws? Then can I afford to have red streaks associated with grey areas of the coat + other areas like tail base, caudal thighs/shoulders? Or do I need to make it like...an auburn or other naturally "red" colour. She will have deep yellow/amber eyes.
Special Attributes: None
Alignment: Lawful evil
Personality: Larisa is cold and distant, even with her close family. Her respect and adoration are things to be earned, and she is not quick to dole these honours out. She is more lenient with her children and can’t deny the maternal instincts she feels towards them, but she was never the nurturing type and still holds them to a high standard. Needless to say, she is slow to warm to others and does not aim to surround herself with companions; despite this, she is courteous to acquaintances, if only to leave doors open if an opportunity in the future arises.
Quietly ambitious, she carefully weighs up social interactions so that she gives away only what she needs to; however, this is at conflict with her loyalty to the pack and family, and this can be a source of discontent for her. After being demoted from the position of ‘acting matriarch’ so-to-say, which she accepted graciously, she could not help but develop a feeling of resentment at the loss of this position. She tries to suppress this feeling for the societal good – or so she tells herself to maintain the status quo – and yet it has soured her relationship with her niece.
Backstory: She was disappointed in her sister's actions and felt that disownment was appropriate given the circumstances...however couldn't shake a feeling of regret and sadness at her leaving which she hasn't fully been able to come to terms with. She supports Manea's claim to being the new matriarch, but harbours some resentment after being demoted...she offers her full support regardless, but definitely feels differently towards her niece.
Plots: Happy to make some conflict between her and Manea if you want! Otherwise just happy to feel out the change in dynamic after Manea becomes matriarch c:
