If you title this piece, maybe it can be called Twilight Raid or something. A good font to use is Comic Sans. It comes with most computers.
But seriously, you really need to put more work into this, cleaning up line work and edges and solidifying forms, making straight line actually straight, checking perspective. You are fudging too much on this.
Make the main machine much more finished. Pull back on the lens flare special effects.
i would imagine that if it was a grid of distruction.....wouldnt it shoot two at once....maximize the destructing while optimizing the time it would take.
plus it just seems weighted wrong
i dont get the light .....
the random strokes have no meaning, therefore are distracting
the city in particular...ive seen strokes count for something, shapes representing buildings, and such
you need to plan this out more i think, tighten up your work
and if there is going to be highlighted strokes, like on the ship, make sure they follow the form so they make sense, and not distract the viewer.
