I've seen these before, they are even more impressive if you have examined the figures before modifications, as they are sold, with massively out of proportion barrel chests, thick necks, and ill fitting clothing that bury the figures necks, so that the collars are practically up to the figure's ears. (Seems the manufacturers play to the majority of consumers who are dopey and prefer unrealistically muscular over accurately skinny... which goes back to our best in show diorama conversation...) The articulation doesn't permit fluid realistic poses as these models show. There is a lot of kitbashing and tailoring involved in this work.
Another thing I really like about Luca's work is his figures often appear to be doing something, or are off balance, frozen in action. Looking at your typical resin WW2 figure in 1/35 scale and up, you would get the impression that WW2 was fought on completely flat terrain by guys standing around at ease, trying to look nonchalant.
There are a few more figure artists working in 1/6. Paolo Ventura is another Italian, probably better known. His figures are more about setting a mood, which he does effectively. They are mostly rather creepy. Interesting work.
