A little more help:
"Eres" is like a permanent form of "you are" so you would say, 'Tu eres una mujer' (You are a woman) but to say 'You are here' use Estas. So change eres ausente to estas ausente. "El cielo es oscuro" ideally would be changed to esta oscuro; same idea.

Dulce is descriptive---sweet. Dulzura is sweetness, which would also be more appropriate. Hope this helps and that I didn't sound like a teacher.
