I think the first one is the only one that's decent. The others aren't very good looking. One thing I must say is that the Text and pen tooling are really good. The edges of the render look bad, you should add a jittery smudge effect to the parts that look choppy, in order to add a small "fading away" effect, and at the same time creating more depth and blending. There should also be a light source, which could greatly improve this.
If it was shrunk and the text could still be seen that way I'd change the first one into my Avatar and rename myself Blue Phoenix. Seriously I like the first one!
i like the third one i like how it has shattered crystals it would have looked nicer if the whole background was the shattered crystals and had riku in the middle blue is a nice color for it
