Both are nice, as you can see in the first line of the second paragraph (Rafael es simpático) and the first line of the third sentence (Yesica es simpática). What they do not have in common is their hair color, Rafael is dark haired (moreno) and Yesica is blonde (rubia). Both live in New Jersey, (vive en Nueva Jersey), but Rafael is African, Mexican, and American (Es africano, mexicono y es africano, mexicano, y estadounidense) whereas Yesica is Columbian (Es de Columbia).
I'm sure this isn't everything, but I hope it helps!
