I was trying to describe a brewing storm in a somewhat articulate/poetic way and while choosing how to phrase it I came across this:
In but a few moments the everpresent azure tint vanished from the visible sky, the entirety of which is now enveloped by a large, ominous tempest.
In but a few moments the everpresent azure tint vanished from the visible sky, the entirety of which has now been enveloped by a large, ominous tempest.
As you can see, whether I leave it as "is now" or change it to "has now been" the sentence is still in the present tense and the meaning is conserved—for me at least.
So my question is, is there any inherent difference between the two?
