Hideous badly-made characters of DOOOM, please help me I need help *whimper* Options

[NumptyScrub]

Pursuant to the latest Session of DOOM I am linking the 2 characters I created that have survived the cut, in the hopes that minds immeasurably greater than mine can point out all the schoolboy errors, idiotic choices, and plain retarded munchkinism and show me how to make them better.

Not necessarily more powerful, but better balanced, and capable of taking their place in our doomed TPK-waiting-to-happen with heads held high (or at least ducked behind the nearest piece of street furniture while Lone Star or the Yaks empty a van full of ammo into it).

First up is the one I am playing: Caine T. Longshot (chummer file) who is no longer a sniper, as I think I fired 3 rounds in 7 sessions, and the Barrett 121 we bought him in session 3 is still in the wrapper. I freely admit the move from adept sniper to Mys-ad ninja was to take advantage of karmagen, as you can Initiate in karmagen (IMG:style_emoticons/default/smile.gif)

Second is our Faceman (chummer file) who I built after realising we had no character with a Negotiate better than 4 dice. I had also (unfortunately) just been reading a post referencing pornomancers, hence this dubious one-dimensional monstrosity. He is an awesome face, but no use at anything else particularly.

Edit: I forgot to mention that we were given the limitation of only material from SR4A or Arsenal (no Street Magic or Augmentation etc.) which is why you may see glaring omissions of stuff you were expecting to see. I just used Chummer set to SR4A and Arsenal, with (where possible) a copy of the books on hand to look up descriptions.

RIP Mr. Happy Punch (chummer file) who was probably the most (accidentally) balanced character I built, as I wasn't sure what the player he was for wanted to play as. He has since been "retired" into the hacker char that Zod's player built, when we realised this whole Matrix thing was actually bloody useful after all.

Please feel free to pull no punches, I am old enough (and ugly enough) to be able to take criticism un-edited, and stupid enough to let the true bile flow past unheeded. Hyphz willing, after taking your sage advice into account I will be providing freshly rebuilt (yet again) characters for him to veto as he sees fit (IMG:style_emoticons/default/smile.gif)
