Beautiful refers to the looks alone
lovely corresponds to the whole
this being the inference I read just now
How far is it exact?
I do not know.
Beautiful is an impression
it being a something extra ordinary
not only the features in particular
being also the surroundings altogether
this being so of a scenery in all.
Beautiful is an exclamation
while seeing a person or architectural marvel
that which captures the eye in particular
captivating the spirit altogether
being an indication of exaltation.
Lovely, 
they say is an endearing quality
need not point out to the looks alone
being focused on a lively interaction
a charm in speech and behaviour
that being also felt not seen.
Lovely, is one that officiates an affection
coming from the depth of the heart
being very intense and significant
getting through the whole being with rapture
being a process of enchantment
There being s subtle difference , no doubt
with beautiful and lovely being both 
breath-taking
a desire to see once again being predominant
that both these words connote to a qualification
that being sublime and unique in the presence.
