I built this Gouf Ignited with a full paint job.
I only used stickers on the mono-eye.
Initially, I was going to paint it in the standard light blue color scheme, but I ended up using Heine's colors.
The runner had "Z.A.F.T frame" written on it, so I'd love to see HGCE versions of other mobile suits like the Jinshi Gudin and (though I doubt they'd be interchangeable) the Zono Ash.
And maybe some Gundam-type remakes like the Saber Gaia...
