The second last picture is unblended. (There really wasn't much to blend on this one so it's not an easily noticeable change.)

I use the colorless blender to rub the area where two colors touch eachother (In the second last picture, you can see the unblended color sections in the sun as an example.), you can make a decent gradient this way but it desaturates the area. So you can take the lighter of the colors an re-fill the area that you blended and desaturated.
