Yeah, but those people are good at making signatures. When you get the basics down and know how to compose a signature to make it flow and give a good feel then you can do that. You have yet to master any of the basic principals of tagging.
I could go through each tag and explain what is wrong, but I can tell you are one of those people who don't take critique well so I would be wasting my time. So here is an overview:
Blurring the hell out of a piece doesn't make for good depth, good depth is achieved through light and shadow, with subtle blurring and a good composition of effects
Random lines and cinema borders ruin a decent tag as per all of your tags, learn when and where to use border - and hipster cuts aren't cool.
Composition is very weak, there is no flow in most of the tags, and duplicating a render and moving it around in the background doesn't make for a good background. It makes for bland colors and usually looks like a vomit of effects.
Learn lighting, most of your pieces have lighting elements but it isn't reflected anywhere else in the tag. Study photographs and read up on how light works that should help improve the lighting.

Now if you don't think any of this is relevant to you then ignore this and continue what you're doing and keep making mediocre tags.
