Model Rocket Launcher

At the moment I don't think it suits TF2's style, it seems too blocky and futuristic, look at the other weapons, they're much rounder and more minimalist with very little extra that you'd imagine would be needed. The flamethrower is simply a propane tank attached to a pipe with a fuel filler for a trigger and a flame guard, everything seems almost home-made and you can imagine a use for each bit, I think you might be heading in the wrong direction style-wise but take a few other peoples opinion first before making a decision.

I suppose you intend to then submit the model to contribute and the modeller gets nawt?

It's blocky, it's boring, it's not in the proper style, and it's downright ugly. As much as I hate to say it, you really should just start over.

Review the style guidelines, and move out of sketchup, you're not going to get anywhere in that.

Pick up a 3ds max trial, or blender, and then start really making things.

Huh. In my opinion it looks like an okay Direct Hit replacement, though yes, it is a bit too futuristic.

to see which colors match, and correspond to each other.

Did you unwrap it?

It looks too much like halo.

Everyone needs to stop wanting halo crap in my TF2!

It's ruining my experience!
