Attempting to Sculpt a Hybrid

So I've been a little busy recently working late and on some Imperial stuff so I haven't had much time to work on the Cult.

However, I've decided to make a start on my Hybrid in sidecar project, beginning with the Hybrid passenger. The passenger will just be the upper body of a Hybrid poking out of the sidecar wielding some sort of weapon (as opposed to manning a heavy weapon like the Space Marine attack bike). The easiest options available to me were to simply use the upper body of an existing Hybrid model but I decided against this as the metal ones are tougher to work with and, as they are about £7 - £8 a model, the project could get quite expensive if I messed things up. The other option would be to use a plastic Hybrid but they are all Second Generation Hybrids in my force and a more 'primitive' Hybrid in a sidecar wouldn't seem right to me.

Instead I decided to take a bit of a leap and build one using plastic Catachan parts and heavy greenstuff and milliput sculpting and, as I'd only really used greenstuff and milliput for small parts or gap filling previously, this would be my biggest sculpting project to date.

At present, I've only really started on the torso (waiting for the greenstuff to harden at the moment) but its not looking too bad for a start.

Using a metal Hybrid as a base, I decided that the first thing to work on was the 'ribbing' that can be shown beneath the armour plates which I made by filing down the abdomen of a Catachan torso and then covering with greenstuff and rolling the rear of my knife around. Its not perfect but I plan on tidying it up as it dries and most of it will be covered up.

The armour plates will probably be made using milliput (as it holds an edge better) and the arms will  be a collection of Catachan and plastic Hybrids.
