Not really. That's actually the torso's general shape, it'll probably look a lot better with added arms. As far as that small red dot below the cockpit goes, you might have to talk to NaXx about it. Personally, I think that's an energy weapon slot... there's a ballistic slot right above if you zoom in a bit.

Arm's hole must contain an arm [/sarcasm]

Probably I must sprite something, but nobody have requested it since this moment...

Since MW arms do not move afaik, I'm just going to stick them on the mech body itself. Feel free to throw mech bodies and legs at me, or weapons if you want, and I'll stick them in. It's a pretty quick turnaround, just an Actor and perhaps a new turret.

That'd be because the Vulture/Mad Dog has the same pelvis and leg structure as a Mad Cat

On the note of arms, the Timberwolf's would pretty much look like a short corrugated pipe from the side.
If any of the spriters need diagrams of the mechs (specifically line art front and side), try HERE.

Also may I suggest adding the Vulture? It looks awesome from the side, and all that needs to be sprited of it is the torso section, and I'd be happy to do the pixel lineart of that.

You may, even though it has already been planned, mainly because that's a perfect pic for leg-making. Also, why does that page about the Mad Cat require Quicktime?

As it plays music in the background.

I am offended by the inherent lack of Bushwacker in this mod.

After see this Bushwacker I second Lambda's request...
Also, a preview of FAFNIR incomming mech, productive criticism wanted :

That's an Asp, NaXx, not a 'Whacker. I'm working on the Bushwhacker right now.

Look down, keep looking down, little cricket
