Facebook banner design

NICE! I have always wanted to learn how to make that trippy effect... maybe you can teach me or show me to a yt video??

nice and clean, i like it.. good use of fonts and colours

I love the purple color theme. I like the idea to use 2 triangles to combine it to a pentagram. And it's a good idea to put a picture or something in one of the both triangles as counterweight, but I don't like it how you did that. The mountain with the nuke explosion on it, makes the whole design optically overloaded. It's too much. Dieter Rams said: less is more. I would to try to reduce it.

This FB image is great, but is it scalable to a responsive design?

That looks truly amazing mate
love the creativity on that!
