sergei that was a great post with som excellent observations.
You're not the only one to have spotted all those errors, I made a similar post on another thread here.
I still think he's lovely, but the faults with the costume do bother me somewhat.
I think which can be clearly demonstrated with this comparison photo.
As you point out the length of the duster is too short. The sleeves too short and too narrow amking his writs look too thin and his hands even more enormous. The shirt's inlaid 'strips' are too dark and too wide for this scale. Also the dusters lapels are set too far back on his shoulders as you can see.
The vamp makeup is wrong, but strangley enough not as bad as some sculpted attempts I've seen.
I also would have liked more emotion in the face, but as I know from my dealings with my friend who is a senior portait sculptor for Madame Tussauards in London getting a good likeness is actually a lot harder when a person smiles then when he they are 'straight faced', so I can't blame them for taking the easy option.
Also I suspect that this likeness was created by using a scan, for the sculptor to work over just as the original 12 ich figure was which is probaly why his face is so neutral.
You can also tell this sculpt has been based on a later season version of Spike, as he looks sublty older then in he did in season two. I suspect that the toy firms may have access to the scans that were made of James during season seven for the the end of chosen.
All of that aside I'm more then grateful that they have chosen to give this wonderful character the PF treatment and to have him released so soon after the Buffy figure means that they must think that he will sell well.
I know If I could afford to get one I would at the drop of a hat!
