Lets see if I can remember the bits and pieces 
turbo squid - ED-209 - re textured with Worn leather matl and colors changed , details added in p-shop.
Daz -V3- re posed and added new skin textures
Project Lara - gunbelt - modified and re textured
RDNA- helmet and goggles- re textured and modified
she hulk tunic 
Background - small piece used from a freebie jpg. here on R'sity
Cannot for the life of me remember where the back ground ships came from -I think as a resource from Deviantart - heavily modified and detailed.
Background and ED-209 were rendered and saved as a tif. imported into p-shop and cleaned up and detailed then imported as a background in Poser and the figure was rendered matching the light source and color from the first render. Changed the camera to a more amorphic lens size to get the "heroic" look, applied careful depth cueing to get depth of field .
I do not think you are required to have a BFA in order to do this - on the contrary this program did not exisist when I was in college ( I graduated in 1987) The point I tried to make - (appearently not too well) is that the basics of all art training apply to digital as well as traditional (analog) art . Color theory , perspective, form,symetry ,composition are all important - poser is a tool nothing more -nothing less. I kind of regret starting this thread cause it seems to get some a bit fired up- sorry however I have learned a lot about the history of poser .
