All way too washed out, none of them have a clear focal point, the only one that comes close is the spongebob one, but when the render of spongebob and pattrick are that big it's not hard for them to draw the eyes attention. The washed out stye is actually a alright, but when your using over the whole signature it looks horrible and physically hurts my eyes. Learn to use it on a smaller scale too draw the viewers eyes to little points of detail in your work, and use it as a moderate form of lighting in small parts of your art. You just need to start learning the basics, i.e adding depth to the image, getting lighting correct, focal points, and manipulation on your piece. Nail them and your work will start to come along. As someone before said it just looks like you added clouds over your pictures, and then and then added some form of lens flare, or a white overlay with some bad brushing, your looking at the piece as a whole and doing everything on too big of a scale, try look at the finer points in your pieces and improve them.
