Sure sounds like a lot. We never think things will take as long as they do. That's why I started plotting out hard numbers.
How many words written-how many more scenes to write.
How many image plotted out.
I was making it renders while writing the story but it is easiest for me to get the writing done first and use early renders as references and jump-off points for later renders. Then, I can see how many more renders I need to do and divide that by how many renders I can do in a week.
Some days I can make dozens of renders. Sometimes, it takes me an hour to set up a scene. Then there is the times when I decide I'm tired of this angle and I change it all over again and double my work.
Good luck!
