2nd is pretty darn hot. Only prob with it would be that spot near the render's head. And some different color other than all that brown D: First the bg is cool but the render is so dark which clashes with the bright bg imo
The first and the second look over sharpened. On the first the blue lines for the text don't fit i would change it to the yellow maybe. The color could be better in it as well. And there's a perfectly good light source, but no lighting that i can see. The second has very poor lighting as well, it makes it obvious that you got a white brush put it on top of her head and reduced the opacity. The third seems..kind of random, i don't understand what you were trying to do with it at all. I think the first has some potential but there are huge flaws that need fixing as stated above.
