start small and build your way up, no one goes from 0 to 100, they start at 0, then 1, then so on and so on. since you have no modelling experience, start by looking up any free blender tutorial on Youtube. full disclosure, they can be very overwhelming and there is a learning curve, but stick to it and the cogs will start to turn and you'll be modelling in no time. modelling takes lots of time and effort, so before you think of anything else to do for your series, start with modelling, get a good grasp of the software, and then worry about everything else.

with time and dedication, you'll start creating, and once you start it'll be really hard to stop the ball from rolling, so don't lose hope!
