I have painted my second figure of the House Harkonnen blister (I promise, the next picture will be of all the group and not only one figure) and I can re-afirm they are very nice figures, really easy to paint. The pack of weapons is also very useful.
So here is Feyd-Rautha Harkonnen:
Also, its card to use with the "Gruntz15mm" rulebook. I know they are 28mm figures, but I think it ican be very easy to adapt the rulebook to them (in fact, I expect to use my old GZG 25mm figures with it...).
Cheers!
