Mario,
There have been many times over the years when I start with a particular diorama idea and it either morphs into something else or new figures come out on the market that I want to build more and the idea gets scrapped altogether. The one with the water buffalo probably won't get built. The one with the shaving cream joke got changed, but I did build a small 2 figure vignette using the sleeping Soldier and then a conversion of one of Bravo 6's M79 grenadiers as a humorous entry for a show I entered a couple of months ago. Later today or tomorrow I will post a picture of it on this thread to show you.
I've used plenty of Hobby Fan figures and have used the equipment such as their canteens and ammo pouches for quite some time. They are also very nice figures. I have done several dioramas in the past using Hobby Fan figures. The last one was my "Just Another Morning In Vietnam" diorama that I did for the last Vietnam building campaign on Armorama.
I agree that the latest two from CMK are pretty nice figures. However, they are not Marines. They look more like 9th Infantry Division Soldiers during the May 1968 Mini-Tet. The sculptor did a pretty good job on most of the stuff on the figures. I wish he had added some thickness to the claymore bag the sergeant is wearing, but with a bit of putty the problem is solved.

Cheers,
James
