Finally had mine painted and put Anakin back together.
I decided to keep the original Sideshow body, since I think its height works better for Hayden's height, and the lanky build isn't an issue with all the layers of clothing. Despite the issues of the old Buck, it has to be said that it has a great range of articulation.
Back to the head sculpt, it really is a beautiful sculpt, easily the best Anakin/Hayden sculpt there is. I think it has a couple of issues though.
First off, the hair in the back doesn't work too well since it's sculpted flush to the back of the neck, so there's no space to accommodate the clothing. Sideshow's old sculpt was better designed in that regard.
Secondly, the sculpt seems a tad small/narrow when compared to others.
Regardless, it's a fantastic sculpt, and the figure really shines now.
Looking forward to Obi Wan if there are any plans to make one.
