More Work on the Contemptor

I decided that I needed to do a little more detail work on the Contemptor Dreadnought.  To whit, I spent a bit of time working on the weapon arms.  I decided to go with the Multi-Melta arm because it allowed me to try that scorched metal effect.  I got the effect by mixing Sotek Green with Balthasar Gold and slowly layering up to the brightest part at the end.  I'm pretty happy with how it turned out, but it's not quite the scorching effect you see on other models.  Clearly, I need more practice, but I think this was a good first effort.
