Is this correct and natural?

Jack opened his eyes. A thirtyish woman was sleeping next to him, her dark hair sprawled across the pillow, a riot of loose strands. She rolled over and her unfocused and somewhat confused eyes met his. Her gaze drifted from Jack's eyes to the pale blue blinds. The winter morning was bleeding through holes in the curtains.

Jack opened his eyes. A thirtyish-year-old woman was sleeping next to him, her dark hair sprawled across the pillow, a riot of loose strands. She rolled over and her unfocused and somewhat confused eyes met his. Her gaze drifted from Jack's eyes to the pale blue blinds. The winter morning was bleeding through holes in the curtains.

See above. I'd probably say "A woman of about thirty ...".

Look at the last two sentences. Does the window have blinds or curtains?

I thought they are kind of the same. I googled and realized that is not the case.

To avoid the repetition of "curtains", can I use drapes? If not, what word can I use? I mean I know I can use a pronoun, but can I also use a word?
