Thanks for the feedback all! It is appreciated!
For the best critique, you probably need to post some pics wearing it; even if you don't have a flight/jump suit yet, at least we can get an idea of placement and spacing. If you need to make the body attachments first, you may want to hold off painting it for now....
I wish I took photos now when I taped the whole kit to my body a couple months ago. What a pain it was to line up and tape lol, I will post photos of this before final attachment. Do you recommend attaching snaps/velcro/bolts prior to painting? If so, could you explain?
I would start with the base coat over all the pieces so you can get a uniform surface color to see about any defects.
My question is what dd you use for the vent at the bottom of the jetpack?
Unfortunately I don't know what was used for the vent, as I purchased the jetpack second-hand. I can tell you that it is a homemade jetpack, made mostly of bondo and thin wood support. I believe the vent is either wood or plastic and approximately 2" in diameter. Hope this helps a little bit.
I like what you did to the Mavericks. But I think they still need some modding in the revolving barrel section.
And could I get that assistance on the wrist rocket? 
I'm glad someone else likes them, lol, I was wondering about those. I put as much or more time into those than the gauntlets. I'm like you - I want to do something to the revolving cylinder, but I can't put my finger on it. I thought about drilling holes or cutting holes. On the other hand, I've thought about painting a unique pattern on them. Do you have any suggestions here?
The rest of this post refers to the rocket:I used a 1" diameter for the main portion, and an overall length of about 8". Here is a list of the parts I used:
Main body: 2x Clutch Pilot Tools cut & epoxied (I THINK this is the right part #)
http://www.autozone.com/autozone/parts/Motormite-Clutch-Pilot-Alignment-Tool/_/N-9xy4z?itemIdentifier=726315_0_0_I sanded down various 1/2" to 1" PVC pipe fittings for the spacers and rings. I don't recall exact parts, as I purchased one of each unique fitting (couplers, end-caps, adapters, etc.). Mostly purchased between 1/2" and 3/4" fittings though.
For the large cone, I sanded down a Pull chain for a ceiling fan from Home Depot:

For the small cone, I used a 1/2" x 1/2" (at widest points) bronze nozzle that I found in Lowes' Plumbing section (with the small plastic tubing & clamps). I used parts from this section of the store for attaching my Right gauntlet's tubes also.
The orange plastic inside that cone was cut from some spare plastic lying around. I had to place something here because the the nozzle mentioned above was too wide open. Wood dowel would have worked.
The tip was a spare steel pin, which I had cut off of a heatsink. A thick paperclip or sturdy metal could probably be used. Make sure it isn't sharp.
The opposite end of the rocket was some PVC fittings glued side by side. On the end is the skinny portion of the Clutch Alignment/Pilot Tool, with a PVC fitting cut to slide over it.
Don't rush when sanding or gluing, or it could end up crooked. The pilot tool doesn't adhere well to regular clear epoxy; I found this out the hard way when I took the Exacto knife to the splines. It does fine if you cake it on there, but the splines are tough. I'd recommend trying the Plastix epoxy. I used the clear one because it runs and fills cracks better, so I thought it'd be easier clean-up on the splines.
