Over the past few years I've had a few requests for work. I feel the need to give a little insight into the effort required for a single piece, for serious consideration before asking me for work.
My last piece was a weretigress done in Blender. I did not time myself (I will start doing so), but here are some rough estimates:
Research: 4 hours
Design & layout: 2 hours
Background: 4 hours
Pose: 10 hours
Textures: 2 hours
Shading: 24 hours
Lighting: 2 hours
Hair: 4 hours
Fur: 12 hours
Water effects: 8 hours
Test-renders: 20 hours
All those hours are me, hunched over my machine.
Custom morphs for fangs and claws had been done already (no estimate on those included).
+ Final renders: 90 hours (during which my computer is unusable for anything else, but does not require me to be there)
Going back through my file system, I can see that the piece came together over a four week period, with most of the work being done over an intense final week. It took about 50 iterations to get it to a state where I was ready to publish it.
So you can see that the whole thing takes some time. Granted that this was my first serious work in Blender in a while, so there was a learning curve. I'm expecting to be able to re-use some of the piece in future works, and to become more efficient myself, and to get some better rendering hardware. My goal is to be able to produce something in a single week. I could possibly do lower quality work in half the time. I expect to have multiple things in progress at the same time.
