For a project I'm working on, I'm debating the value of having my cast be entirely made up of non-humans/aliens which do not have a direct analogue to other fantasy species or real animals. I have a bunch of ideas I'm happy with but without visuals I feel like it can be difficult to convey an entirely novel sapient species, much less multiple ones, and expect the reader to keep all that in their head. I feel like this can be gotten away with a bit more in science fiction but I'm aiming for fantasy where the generic post-Tolkien elves and dwarves reign supreme over much of the genre. The few books I know of that manage similar to this are not especially popular or are the least liked volume in their series.
What do you think? Is that likely to be too confusing for readers or should I trust them to retain it? How do I describe these things without it just becoming a painful info dump or vague blob of an idea. Especially with multiple such species running around.
Much of this is for personal work not something I'm expecting to be able to publish or monetize necessarily. Still, I suppose I want to know if this project might be a bit of a waste of time that won't be accessible for anyone else.
If anyone has any suggestions for novels or short stories with entirely non-human casts of different original species I'd appreciate that as well.
