This is interesting to read. Despite being short i really enjoyed the message you passed across. But i really don't understand the line.
"Even so much more so"
It sounds kinda off...
I think it would be better if u had something like- much more so. Or u could use a punctuation between the so and the much. So it would look more like.
"Even so, much more so"
Overall this is a really nice piece.

Random thoughts:

* The title feels like it should rather in some way be in the body of the text. Right now it's promising something too specific, namely that the body will elaborate on what that offer is and say something about the works the crow inspired, and not at all delivering.
* The first two lines are good in a Kay Ryan sort of way. I might try a pared down phrasing though (e.g. A crow's beauty is in being black; even more so when it snows.)
* I have no idea what's going on in L3-4. Or rather, I can perhaps gloss it as "Crows are just birds rather than oracular symbols". That elaborates the title a bit, I guess, but it's still entirely disconnected from the prior two lines and the phrasing is just a grammatical trainwreck.

Insightful poem. I would cut down the second line because the length is I find is to long and seems to cut the poem in a not so good way. Even so much more so I think needs a comma. Overall, nice job!

I love the concise nature of your poem. Driving your imagery hard in four lines, you were not afraid to make hard decisions with your work. However, I find the words 'merely', 'simple' and 'more so' a tad distracting and frankly boring. Try to take a surgical, meticulous approach in selecting your words next time. As if each syllable has been interrogated at length for it's purpose and place in the poetry. This will really suck the reader into the small world you have created, causing her to float back to your work time and again to re-live your tiny, singular universe. 

Ok, I know this might be a controversial opinion, but I really do enjoy titles that are longer and bear weight in the poem :). There's some loose rhyme going on in the beginning of this, between "fact" and "black", and "so" and "snows". Was this intentional? If so, have you thought about maybe carrying it through the remainder of the poem, to give it a more uniform feel? If not, it's something to consider. Don't make it too rhyme-y though, because I think with this kind of language and subject manner you risk losing the audience to gimmicky language and cheap rhymes. Nice work!

The crow’s beauty lies in the simple fact,

that they are black, even so much more so, when it snows. 

Merely present ; bearing news

forewarning transformation.

I think crows probably offer up something more to society than inspiring creative genius
