Thank you for a thorough explaination.

1. Try to avoid slang in your writing, such as "a whole bunch of...." They confuse,annoy and discourage your readers.
2. Never put a comma before that-induced clauses, such as "that the poet vividly and incisively...". Besides, the clause led by "that" in your sentense doesn't modify "envisagement".
3. More than several cases, I found, in your sentences, the subjects do not agree with predicates,especially in relatively longer sentences.
4. Tense. Such as this one, "After I wake up, I will only see..."

Ok, enough hammers from me for today.
