Lushwater: Nice URL, posts, theme and banner. I dislike her choice of SCM player, I'd recommend a plain white one. Her posts match each other perfectly along with her URL. I'd assume her followers are around the 5k - 6k mark. 

Aigwa: Lovely theme, posts and URL. Although her theme is gorgeous, it is slightly overused and I'd recommend a new one. Also, I'd recommend a plain white SCM music player. Finally, her posts are gorgeous although a majority of them are blue except a few recent pink posts and I'd recommend that she sticks to reblogging blue as it gives her blog more continuity. I'd assume her follower count is only 100 or so.

Wholvies: Amazing blog! Love the vibrant combination of colors displayed through the posts and banner. The only things I would change is the color of the banner and header links, perhaps to a more subtle color such as grey or white, just to keep focus on the posts, rather than the links. I'd assume her follower count is only 200 or so.
