I tried to check things myself but I still have a few doubts. Please, have a look at them.
1)A novel is retrospective when the narrator recollect memories from his/her past.
2) Friday is similar to a European in his complexion. However, he describes only few negative aspects negative physical aspects about Friday.
3) His hair is not curled like wool and his skin is not black but tawny.
The reference to the nauseous tawny shows that Robinson doesn't like the non-European races. In addition, he says that his nose is small and this is in contrast with the flat nose of the negroes.
4) Another feature is that the hero is always a middle-class man with his problems and for this reason the reader sympathises with him.
5) You paragraphs include long-winded sentences where punctuation rules are not respected.You often fail to capitalize words after a period.
6) He decides to make his cave as comfortable as possible. He also makes furniture and pots from clay. In addition, he builds a fence around the cave to protect himself.
7) Moreover, he hunts goats but when he is running out of gunpowder, he decides to start a goat farm.
1. OK
2. Friday is similar to a European in his complexion. However, Crusoe describes only a few negative aspects about Friday.
If you don't put Crusoe's name in there, "he" would be referring to "Friday" -- and certainly Friday wouldn't be describing himself, right?
3) His hair is not curled like wool and his skin is not black but tawny.
The reference to the nauseous tawny shows that Robinson doesn't like the non-European races. <~~OK up to this point, but the "he" and "his" need clarification in this sentence. ~~>In addition, he says that his nose is small and this is in contrast with the flat nose of the negroes.
4) comma needed after "problems"
5) "Your" -- all else is fine.
6) He decides to make his cave as comfortable as possible. He also makes furniture and clay pots. In addition, he builds a fence around the cave to protect himself.
(If you put "from clay" after "pots," it reads as if "furniture and pots" are made from clay!!)
7) Comma needed -- all else is OK.
(Do you see where the comma is needed?)
