I'm making some "advertising" posters for Xonotic which our mappers can use for their maps (also usable as screens for pcs or tvs)
The work is still in progress:
I think that where the lines converge distracts to much from the phoenix. Maybe blur the lines and brighten the phoenix? Or make the phoenix solid and stand on top of the lines.
try making a few where the logo isn't in the middle. like try the top right corner, and have something else in the bottom left corner to balance it. (like maybe one of the character models posing heroically )
