I always liked the very lean version of the D&D Troll with long arms and a pointed nose. There are dozens of interpretations of Trolls but for me this is the original, likely because it was the very first version of a Troll I encountered while playing the old AD&D Gold Box games.
While actively looking for fitting troll models I happened upon the Patreon of Manuel Boria, who had just done a set of them which fit the image of a Troll in my mind very well.
