the largest flaws in every single one of your tags are coloring and lighting. Your lighting in every tag you make is just bad. Using a soft brush to light makes the lighting look totally forged. There is only one tag that I've liked with soft brush lighting, and that's rouges'. Your lighting always looks forged. As for the coloring, its done better, but it still needs a lot of work. Your effects are also repetitive and starting to bore me.
I personally love the colors used, i think the render could be blended in a 'teeny' bit more though. gj hun
