20Hundred If you are a new to writing, it would actually better if you stick to the cliches and commonly known terms. It's easier for you and it's easier for the reader to imagine and understand everything. Eg. (elf, dwarf, gnome) There are some web novels that come with completely original lifeforms or those that take from more obscure legends when creating their characters, but they also include detailed descriptions or drawings of said lifeforms, since it's generally hard to imagine a new lifeform even if you give half a chapter long description about it. But when you say elf, everyone knows what an elf is. Even tho it maybe cliche, but no one really minds that.
Just to show you an example why creating new lifeforms/character isn't easy and how others do it;
Her hair was black, styled in an asymmetric, short ponytail that was tied off with a string of small beads, and had a pair of hair clips on her left bangs. Her skin was a reddish-purple, and while her head was fairly human in shape, her face was the most monstrous of Boxxy’s entourage. Although it looked human at its core, it bore several bug-like features that drew attention away from its natural beauty. For one thing, she had two compound, bug-like eyes that were solid black and slightly reflective, and she had a pair of crescent-shaped markings on each cheekbone. Her normal-looking mouth was surrounded by a set of four, short mandibles that poked out from around the corners of her lips and loosely resembled tusks. A pair of black, beetle-like mandibles grew out from the sides of her head around where the ears would normally be and extended all the way down to in front of her chin. They were curved, serrated, and looked sharp enough to bite someone’s arm clean off. Their pointed tips clacked together incessantly, giving off a soft, chittering noise.
Surprisingly, her actual body was also mostly humanoid in shape, with two arms and two legs. What gave off the earlier impression of a spider were the 6 spider-like limbs jutting out from her back. They were sleek, covered in black chitin and tipped with long, scythe-like blades that were part of the limbs itself. She must have used these to crawl along the ground earlier, and those shiny blades looked like they could turn a man into mince meat in seconds. They also looked to be about as long as her primary pair of legs, although the way she kept them curled up behind her made it hard to judge.
Her breasts were large and perky, although not quite as big as a succubus’s, and her thin waist and wide hips gave her a fittingly waspish figure. The upper part of her breasts were covered in black-and-yellow-striped chitin that ran up to her collarbone and extended upward to protect her neck and throat. The smooth-looking material also formed a pair of light shoulder pads and wrapped around her back and sides, as well as covering up her nether regions. Her stomach area and the underside of her breasts were left exposed, prompting Kora to give her a quadruple thumbs up while saying ‘Nice underboob!’
The Stalker’s upper arms and thighs were left similarly unprotected. The black-and-yellow carapace extended down from her elbows and along the length of her abnormally long forearms, almost like a pair of gauntlets. Her arms ended in a pair of thick, armored wrists, and each hand had three thick fingers tipped with a long, sharp claw each. These were clearly not appendages intended for grasping tools, but weapons designed to rip people apart.
Her legs from the knee down were similarly covered in the same carapace. Two long, dagger-like growths jutted out from the front of either of her toeless feet, almost like a pair of knives in a V-shaped pattern. The carapace on the top of her feet was shaped to vaguely resemble elongated skulls, while a number of sharp spikes jutted upwards from around her ankles.
