Your results are excellent :) (To my surprise, I actually found that I quite like doing greenstuff things, like sculpted bases and so forth.)
I’ve done so much dumb/amusing/fun things with greenstuff over the years. Never a full sculpt, but a heck of a lot of modding and of course gap filling. The biggest project I ever did was my custom Shepard toy… but in 40K-ville it was probably the World Eater Dreadnought, a piece I’m still proud of. Then for some reason I decided to do a custom Templar army with a bunch of knightly mods to each figure. Too much effing work, but they look different at least. One of the reasons I wanted to do some Ultras, aside from loving their color and fluff, was to go back to a largely umodified army.
Dang this makes me want to dig through my closet for more models.
