Well, thanks to the encouraging comments regarding my first attempt at sculpting 6mm Sci-Fi infantry here on TMP, and combined with subsequent offers of work 
received after I posted on TMP.
I can now offer another "How I sculpted" article at MiniGerm for all those interested in how it's done! (Well, my way, at least.)
I'm also pleased to announce the miniatures are being produced by Brigade Models, possibly as early as next month.
So watch this space for more 6mm infantry, and feel free to comment on the minis so far!
