it is quite hard to get it that smooth.
I use a mix of greenstuff and milliput which its possible to get really smooth. Would recommend it!!
Some new pics from the workbench.
Something was bugging me about the halflings rifle so I tried to add some detail to it:

Rebased a foundry swat mini and based a Brother Meredith mini. The original Meredith figure leans forward at quite an angle so I've stood him up a bit. This meant some sculpting on the right leg armour and new feet.

More figs ready for priming:

Think I've finished painting the plasma marine. My second marine painted of the current batch!

Thanks for looking!
