Alright, I've been oggling at the wonderful conversions on this site for a long time, and I figure it is time I posted one myself...
I give you Smash-kill! [My UE.net conversion competition entry from a few months ago]
Whole shot:

Another whole shot:

The upper body + Rat-club:

The last thing you'll ever see....:

For my first proper conversion, I don't think it's too bad...
I've changed the leg pose a lot, repositioned the fingers, filled the gaps in the head/shoulders/back, and repositioned the 'clubbing' arm [the arm is bent more at the elbow, to simulate the moment of 'just-about-to-smash-stuff-with-this-rat'....
Thoughts?
I know I don't paint well [very simply] or convert to the scale or standard of many of the members here, but hey, it's a start, I made him for fun, and my gaming group love him!
Cheers.
