Thank you very much. I need you to check these sentences, too.

1) Elizabeth was considered as a political genius of the first rank.
2) The Spanish fleet was composed of slow and heavy ships and that's why Elizabeth won the war.
3)He tells his soldiers to cut trees from Birman Wood and use them to camouflage their advance.
Big sense of guilt (is big appropriate?)

1. delete "as"

2. Elizabeth's ships were lightweight and fast, whereas the Spanish ships were heavy and slow. These differences contributed to the success of the English fleet.

3. OK

I wouldn't use "big" in this context. I'd use "heavy" or "great."
