Ah the vent got placed on upside down, under the light I use when photgraphing the stick-tac gets really weak fast and pieces start falling off. I must have put it facing the wrong way when I stuck it back on. I'll have to make sure everything is lined up correctly before I glue everything down permanantly. Nice catch though

I changed the knee pad, took off the suit shoulder pad and replaced it with a firewarrior pad it's roughly the same size from the front view but changes the side profile of the knee so it looks a bit less blocky. Wanted to post a pic but by camera battery is in need of recharging, so I'll try and get a pic up soon.
The head I was originally going to use a sniper drone controller for but couldn't find it and the stealth suits have roughly the same basic shape so I grabbed one of the ones that had been horribly mis-primed and is all gritty. Sanded the grit off the head and put it to the chop.
Thanks for the comments guys, my construction process is kinda random and I have a lot of differant ideas bouncing around in my head and I'm constantly revising and changing things so the feed back does help me refine stuff and sometimes helps generate new ideas I hadn't considered.
You're welcome to borrow/take whatever ideas you want from this design.
I have some more thought to do on the antennae options and little details but i think I have the bulk of the body design in finalized form the rest is mearly the trim details for flashy show. The missle launchers and other weapons will all be getting an overhaul, the X-88 arms are mearly a placeholder until I can get the FW ones finished up.
I'm thinking that this suit design will form my basic chasis for my T'goshai sept X-8, possibly work up house rules for an experimental runb of suits with 5 toughness to represent the increased armor and differant weapon systems than the standard x-8. Even if my opponents don't want to use any house rules the conversions are worth it because I want my stuff to really stand out from a normal Tau army when it's on the table. I think these suits can be connected to the Tau at a glance but it's also immediately apparent that they are quite differant at the same time.
I'm thinking of designating the design as Mikado
