The reddish splotches are normal and typical of Cavendish varieties (and some others). The older leaves on your plant look sad, perhaps as if they were "burnt" by cold or too much sun. The newest leaf and the emerging cigar leaf both look fine. Leaves folding down during the day, especially if it is hot and dry, is normal. Be cautious about over watering or over fertilizing until the night time temperatures are consistently warm.

Basically, it looks fine, but probably experienced some tough weather conditions.
