Especially in 3D where I have to explain to a 2D artist that I didn't create half of the things I used in the picture, where in 2D I don't have to make such a statement, because every pixel is my own. and how is that different than collage in 2d and 3d traditional art? Just because you didn't make half the polygons, has no bearing on how you work with textures and shaders, composition and lighting. People working in collage don't make the bits they collect to put in their work either, and they seem to be called artists all the same... also, sometimes its fun to take a render that you composed, then use it as a base for doing traditional 2d art, drawing what you composed in 3d, using the 3d work like you would use live models in real life. Draw it and submit it, and let them take a bite outta that one.
