There's a few more things relating to skills that I missed ages ago. I'm sorry for the inconvenience; sometimes I get too carried away personality details that I forget I was supposed to check other stuff too.
The following points still apply to this submission:

b) One advanced skill and four intermediate skills are considered too much for a twenty-four year old. I would personally take some of your character’s intermediate skills down a notch or two. Please revise.

d) Your character’s backstory states that he learnt to play the piccolo during the ages of six and ten. This amount of formal training is not enough to justify advanced skill. Please revise.

The above being said, there are still issues with this character's personality despite the improvement thus far. You have not introduced much new information or deep insight into who this character is as a person. You touch briefly on it, but there is simply not enough substance there for a pass. Introduce new information and a deep insight into who the character is; do not simply restate what is already known with more words than before.
That’s all. Good luck.
