First use of greenstuff

I've never used greenstuff before but I needed to make the join between the feathered plume on my sergeants helmet and the actual helmet look a lot less 'converted'.  I've tried to put a small ring round it so that it looks like something is holding all the feathers in.

As this was my first time with greenstuff I did some research to get me started, I found this section on from the warp really useful.

Having made sure that my hands and tools and surfaces were wet so the greenstuff didn't stick to anything that I didn't want it to I cut of a small section of yellow and blue.  I mixed them in the ratio 1:1 as that seemed to be the general advice and rolled out a very thin string.  I then cut this to roughly long enough to wrap round the base of the plume and wrapped it round. 
Using a modelling tool I smoothed the ends together and pushed it down so that it followed the contours of the helmet and the ridge running front to back. 

I think it was worth it, the join now looks semi official and less kitbashed.

What do people think, any advice for working with greenstuff from your experiences?
