I don't think that's a good render to have used. Try something more HQ and I think you would have a lot better results. It's too dark and not enough depth or definition and the colors are all too dark. Keep up the good work though.

The focal is too blurry as well. I don't like the font work, it just looks like it's kinda placed on there. Try some blending options. The white and green are nice but I would like to see more color and definition.
