I like #2 better. I think it's more inviting and cozy but I do tend to perfer moody and dark over light and bright (althouugh I do like that too, it depends).
The first picture does have cute accessories but too many and it's distracting to me. I don't like a lot of knick nacks and I'm not crazy about the artwork or the shelf/open bookcase he used there. I'm with you I do think painting it a pale blue and putting the Billy bookcase in the pastel room would look a lot better. Also adding floor to ceiling drapes to the window in number 1 would give some much needed warmth and color. I think most windows look better with drapes flanking them, here even if you just used very sheer white or pale pink ones it would add warmth.
