Hello again dear readers. (!)
So the wings are the slightly disappointing part of this as they are pretty badly done. I am going to try and fix them up somewhat but am not going to rip them off and start again. Too much effort, too much risk of damaging the (very bendy metal) model, too much risk of leaving chunks of epoxy resin that I can't remove.
So here is the before and after of green stuffing the wings... it's... good enough. I smoothed and smoothed the green stuff and although you can still see the joins, at least you can't immediately see that they wings are just glued on top of the miniature.

I then decided to use my airbrush to prime the dragon in grey, with a black pre-shade. All using Vallejo Game Air surface primers so far. Body and head still separate...
Once that was done... and seeing as I had my airbrush out... I decided to just go for it and base the thing.
So here's the first coat of Vallejo Gory Red. It's quite a pinkish red but gives us a good, dark base. I love the effect of the preshade with nicely diluted air paints.
Then I switched to a brighter red to get closer to the final base colour
Finally, a very diluted filter of Hexed Lichen (dark purple) in the recesses and Sun Yellow on the highlights. It's important to not just have reds on a red model.
So this is where we got to after last night. Already looks better.
IMO, anyway.
The next question is... to wash, or not to wash?
My options are either...
a) Agrax Earthshade, which would defo work but is a bit boring, or
b) gloss varnish it then do an Oil Wash/Pin Wash, which I have never done before but would be an interesting new technique to try.
