Fantasy Character Concept Art

I have two characters from a High Fantasy series that I would like concept art for. Backstory and personality traits for characters provided down below. I have the characters' physical appearances attached down below as PDF, as well as images for the artists to use as reference. I would like for both characters to be drawn together on the same canvas since they are siblings who work together as a team. (While I do have some specific details listed for these characters, I would like for the artists to use as much creativity and freedom as possible so long as the physical requirements are met) Thank you! :) Backstory: Kaya and Kalani Bryce are an odd set of siblings. Kalani is a human in her late 20s while Kaya is a humanoid boar at around the same age, but he was adopted by their mother at birth. Kaya and Kalani have been inseparable ever since. The Bryces grew up together in a poor fishing village, but when the day came that they both unlocked their ability to wield magic, their lives were turned upside. The Bryces were captured by slavers and forced to become gladiators for their masters' entertainment. Together, the Bryces used their magic to orchestrate a rebellion and secure their freedom. With the riches they seized from their previous owners, the Bryces lifted their home town out of poverty, hired an army of mercenaries, and became a formidable pair of warlords, determined to defend their home land from slavers. As a calling card, the Bryces began hacking off the ears of all of their enemies, whether dead or alive. The Bryces' intimidating reputation has earned them both fear and respect from both their allies and their enemies. Personality Traits: Kaya: brutally honest, gruff, stubborn, down-to-earth, hard worker, slow to trust, aggressive but brave, loves to fight, passionate and fiery-tempered but also very sensitive and caring, extremely loyal to his family, his affinity for rock spells represent his emotional fortitude. More or less has the personality of a typical High Fantasy dwarf. Kalani: free-spirited, strong-willed, open and honest, foul-mouthed, very loyal, likes to tease, down-to-earth but proud of her achievements, passionate, highly capable, hard to impress, prefers the company of warriors which usually means that she spends more time around men than women. She can transform into a Haast eagle (prehistoric eagle). Like her brother she has a soft and sensitive heart that is hidden under a tough exterior. Her scars as a slave hurt her more emotionally than physically. She has the personality of a tomboyish cowgirl.
