I am going to be completely honest with you, apologies if it sounds harsh, please do not take it personally. If I saw this cover on a comic book I wouldn't buy it. Not because it looks bad or anything, the color palette is actually your strong suit it seems, but because it tells me nothing about whats going on inside. You have 3 grumpy faces behind a masked character standing upright. All this tells me is this is a comic with 4 characters in it. Maybe it's got some madmax vibes/desert star wars vibes because of the color palette but that's about it.
It also has the word "negotiations" on it, which doesn't sound exhilarating in any way.
Give me more!
