OK, here's my thoughts. 1: Definitely too many polygons to be really practical. 2: Scale: Poser models are small, compared to the output from most modelling software. I don't have a good figure for the real thing, but something like 15 to 20 inches, top to bottom, would look OK. This would by a y_value range of about 0.2 in Poser, or a little less. 3: Materials: I shall have to work on this, as there seem to be too many materials; A good many of them could simply be something like "Brass". 4: Poser prefers quads to triangles. I haven't checked the UV-mapping yet, but I'm particularly interested in how the microscope slide and the other glass bits are handled. It's a better model than I could have made, but it's a bit lacking for Poser, which has its own idiosyncracies.
