I am huge Eastwood fan and, to be honest, never even considered CE in terms of 1/6 figures...but why not?
I like that head scuplt, whilst the crazy $1k ebay one was maybe overall closer, it was not as tidy and clean - as human - as yours. and for such an expensive ebay buy and a custom, the hat is WAY OFF! Yours is much better, I have an old vinyl (yep still got some of those!) soundtrack of GTGB&TU and the cover is CE's face...that hat is bang on.
Is there some way you can soften the fabric of the poncho so that it will sit right? It looks nice but it is being let down by its inflexability.
I think a Dirty Harry 1/6 would be great, his brown suit, his Raybans, his night-time 'Scorpio' stake-out and rifle outfit, his 7-point star, his .44 Magnum (with shoulder holster, would that be possible in 1/6?), the 'tan suitcase' and his hot dog.
