If this is what you made alone without any pre-made PSD's(graphics which you can edit to your own liking in Photoshop), then you're really talented. If I'm honest, I've always wanted to learn on how to add C4D's, fractals, effects, and such that it would blend to the background/render. I'd like you to try and make two other signatures and then apply to be apart of the GFX Team. I do love the simplicity, and your thinking, the colors match, and the text is also great, especially in your first try.
