I need to replace two sculptures

A weird one but I need to replace make two hand sculptures as per the below link? These are the only photos I can find of the sculptures I have broken. The dimensions and stuff are on there as well.

I appreciate getting exact copies would be near impossible as I don't have the original pieces, but any proposals that can get us close to this finish would be acceptable. You would be doing me an absolutely huge huge favour! I'm in a lot of trouble...

Kind regards,
