Alrighty, I'll ignore the speech bubbles on here (unless you really want critique on them). Let's get right to it shall we?
I feel that the special effects, while colorful and clear enough, look rather wonky. Especially the laser on the top left. It doesn't look like the sparks of the ray match the point of impact. If that makes sense.
Here is a real life example of laser cutting. It's not a ray firing but you can still see the sparks match the point of impact. You can also see that the sparks are straight and not bent. This is because it's debree/material shooting away at high speed. So the trajectory of the material is straight due to its velocity.
You can apply that to the mining of the rock in your cover. Right now it looks like it is spilling ooze on it, but if you do something more like the example here it could really up the intensity of the mining process
