I don't use a rechource pack for biulding. I do have some redstone stuff tweaked (sticky piston sides, hopper arrows, stuff like that), but I disable that when building. What you may be refering to is that I use uptifine and shaders, which is why stuff looks more realistic. It's quite heavy on your computer though.
What would you price an Enderman figure building that is less than a res wide and is like 60 blocks tall?
I wouldn't really do it for how I understand what you want. First of all: I build in creative only. You'd get a schematic. Secondly: I only do stuff that are somewhat a creaive chalange. An organic / artistic interpetation of an enderman: sure. It would probably cost around 50Kr. A recreation of its skin: nope.
