Questions on a Conceptual Character (Pathfinder)
A character concept is not limited to its mechanics. There's nothing I can see that's wrong with anything here, and if it is your concept, then I can't really comment on it, because in my mind a concept includes things like their motivation, background, physical characteristics, and personality quirks. RTJs are also layered with other points of interest, such as the disposition of the applicant, their grammar and formatting, and the clarity of their prose.
My second question would concern whether you're tailoring your character enough for the game(s) that you're seeking to join? I can't speak for other DM's needs, but when I apply to games, or when people apply to my games, the first thing I look for are opportunities to craft a character that suites the narrative goals of the campaign and its setting. What is the culture of the game and what is the theme of the story it wants to tell? What are the needs of the campaign, in terms of its protagonists? How can I fit my character into an ensemble cast? How can I craft an experience not just for me, but for my players and/or for the GM that I'm appealing to?
Not always, but in the past, I've docked applicants for submitting characters that obviously were not designed specifically for the campaign I was getting ready to run. Maybe that's what is turning people off? Every DM is different, and their needs and turn-offs shift from game to game.
