Font and color of the slogan text doesn't quite match with the overall color theme of your work. And I don't see too much work here anyways: generic SC2 background (ripped from the cinematic?), logotext with sc-font and subtitle in another generic font, and that's it.



I quite agree with mrn, looks like a normal work with generic font and a normal background wich I guess is ripped from a cutscene. Try to add a bit of more originality
