You look at Ellenor and the first thing you can take note of is her not that unsurprising size. She is a rather small thing, being little more than four feet tall and built rather thin, not that it is unexpected of a mouse to be small. It suites her well as it does make her look rather cute, with her bright crystal blue eyes standing out in contrast with the rest of her body. Black fur is what is over most of her body, covering her with a lustrous sheen as it catches the light. Her underbelly that is soft white, her short, but dancing whiskers and her three foot pink tail are two things that stands out thanks to that.
The third might not be obvious right away as it depends on the light to stand out. If it is dark, her head fur does not stand out at all from the back, but in light it is revealed to be a deep violet hue. The hair even seems to sparkle as if there is some glitter in it, but if you get the chance to look closer at her locks, you will not see anything so it must be natural. The style she has it in makes it easy for her large round ears to come out without ruining it. It is parted in the center, and curled slightly inwards along the sides, though for the most part it is not allowed to go much lower than the bottom of her ears. In the front, a long set of parted bangs fall to tickle against her cheeks.
She is currently wearing nothing but her collar, letting anyone that so chooses to look see anything they choose to. She is small is once more the first thing you notice about her, but that does come with perks. She has a natural look of grace and agility that comes with her thinness and she might be able to lay some claim to those titles too. After all, she does have a the look of a rodent showing not only in her face but how her hands look a little more like paws, and how her feet are closer to digitgrade than anything else.
This is not to say she comes without anthropomorphic qualities other than her hair. She does have a set of breasts that suite her body well with at the size of a modest B-cup. They are more noticeable thanks to the soft pink of her nipples showing through the white fur over them. Her waist narrows into a nice figure, especially when combined with the swell of her hips, while her too looks to be a nice round and firm thing, even with her tail swaying over it. The best thing is that usually you can find her proud of how she looks, so she does show off.
Her fur's colouration seems to even help show her off too. The white of her underbelly starts under her chin and runs down her front, but when it gets to her breasts, it widens so her breasts are not covered over, then narrows again to an appropriate width. And it narrows once more as it comes to her sex but much more notable is the little band that is over her sex in a reverse peak. The effect is the outline of a heart over her sex, making it that much more noticeable.
It also makes you wonder if her fur is a natural colour, or something else. Either way, it looks very natural on her body.
