When I get bits of milliput left over, or I get cheesed off with modelling I add the left over bits to the structural work on the next 2 I will eventually make.
Breaking up modelling is the best way to do it for me. Little and often as they say. That way I don't get finger prints all over the work I've just done. On a good day I can get a half hour session in morn then another in the evening when the resin has set off.
Finaly a quick picture of all three DragonOgres together, as you can see,still a long way to go.
