After reading it, here is my analysis:
In panic the unicorn flung the vase at the figure, impacting the girl far too many uses of common nouns in my opinion, using 'the' so many times to describe characters makes it sound clumsy and and awkward when read aloud, it also sounds a bit repetitive and vague. I recommend swapping in some pronouns or proper nouns, the vase using the vase twice so close sounds repetitive, I'd switch it out for a more descriptive term such as pot, receptacle, or even 'thrown object' shattered with it's pieces viciously carving out both her eyes I'm not sure whether this is explained further in a previous section but I can't really visualize how a shattering vase could 'carve out' both of someone's eyes, just from being thrown. Some clearer description of what actually takes place may be a good idea, or different wording.. Stunned, the young filly collapsed. With the thief now long gone,this comma need not be here, it breaks the flow the girl awakened, blood still tearing from her eyes,this should be a full stop (or a period, if you're American). Alternatively, for a different sentence flow, keep this as a comma and have a full stop after 'the girl awakened' she crawled to her mothers body, and she sat there with her for the rest of the night. Though I recommend leaving this word out to preserve flow as she wept, in the corner of her eye she felt a familiar glint of light, beckoning her. This feels like a very abrupt stop and feels to me to be slightly jarring. I recommend changing it to 'beckoning to her', or alternatively adding a second part, such as 'beckoning her, calling out to her'. This, of course, would depend on what fits your narrative as that won't work for everything. END
All in all I thought it was pretty good, the only bit that jumps out at me as being noticeably awkward without analysing it is the overuse of common nouns and 'the' at the beginning.
hope this helps!
