First of all, I see right off the bat that you've chosen to give this character penalties in Charisma and Wisdom. While this is not in any way wrong or illegal or a bad idea, it can be difficult to play well, especially since the penalties you gave are in mental stats. I play two characters with Charisma penalties - Seryntas in PS/Freestyle with a -1 and Gillet Tarrym in D&D with the equivalent of a -1 - and I tend to spend a lot time asking myself "Are they showing too much social aptitude?" With this character, you'll have to ask yourself that question and the very odd question of "Is he showing too much intelligence?". Also, having such a low Wisdom will make it hard on the character in the future, when his ability to gain skill points at higher levels is severely stunted. You may be prepared to accept this, and that's fine. But forewarned is forearmed, and I thought I'd give you the heads up.
Also, as far as skills go: It is accepted as necessary to include skills on your sheet that reflect what your character does outside of combat. On the aforementioned sheet for my character Seryntas, despite the fact that he is only comfortable in a fight and totally inept in social situations, he has several skills that show his non-combat passions and the things he knew as a youngster: dogs, raising cattle, getting drunk, etc. Definitely include skills on your sheet to make your character a complete person, as well.
I don't actually know enough Philsys to know if your math looks good; your math isn't complete anyway, so when that's done I'm sure someone with a better handle on it will take a look and give you a yea or nay. I'm assuming the odd bits around your weapon skills will go away when you calculate AT/PA and damage and whatnot for real. I do know that since your MAG = 0, your MP should be 0 as well; likewise, you shouldn't have MAtk listed. Besides that, wait for the sheet to be done and I'm sure PS GMs will be around to double-check your math. They're from the internet. They're here to help.
If it seems like I'm only pointing out the bad parts of the sheet thus far, I'm very sorry, but I'm sure I'll have great things to say when you have a background and stuff up for us to look at. As it is, it's very hard to give you a paragraph on how you used 21 stat points in the proper way, you know?
