I like the concept of this banner. I think you understand what the tone of your series is well, and having the two looking at each other in that conspiratorial way with the red and blue lights effectively gets across "this is about partners in crime."
I think maybe in an effort to compensate for the simple art style, you've maybe put a number of effects on to add visual interest that are kind of fighting against the clarity of the image. The colour overlay and that offset shadow thing are perhaps a bit much.
Another thing that jumps out is that the composition is off-centre, and would probably look better if you budged it to the middle in this case, because the different heights of the characters and the angle of the Egg boxes adds enough asymmetry to be interesting already. ![:smile_01: :smile_01:](https://forums.tapas.io/uploads/default/_emoji/smile_01.png?v=3)
It might also be worth looking at your font. Perhaps rather than using Copperplate Bold, you could look at some of the free "Design Fonts" over on Blambot for something that gets across the comedic tone, or feels more like a pastiche of a crime comic.
Final small change would be that the eggs should be more visible. It's about eggs! ![:hohoho: :hohoho:](https://forums.tapas.io/uploads/default/_emoji/hohoho.png?v=3)
So putting those together into a VERY quick and scruffy mockup:
Characters at the front, with instead of the light all over them, try just a little highlight at each side of them, then the light is behind and they're casting a shadow on it, like they're against a wall, on the run from the police, maybe!? The eggs are being shown like they're some kind of contraband to really sell that fun unique selling point of "crime comedy about egg smugglers".
The logo, you can probably do better by just spending more time on it than I did. I threw down a Blambot font called "Palooka!" and just duplicated the layer so there's a black one of the same text offset slightly under the white one. Simple, but effective way to add a cartoon drop-shadow.
Don't be scared to keep it simple. Having a simple style isn't a bad thing you need to hide or try to make up for with fancy effects. Let that bold confidence in your cartooning shine through! ![:coffee_love: :coffee_love:](https://forums.tapas.io/uploads/default/_emoji/coffee_love.png?v=3)
