Hi there! (please read as I wrote my perspective of work)
So Ingramspark is a self-publishing book company who print and distribute, cool thing to know.
Here's what I have to say:
1- I can make super sharp alien ants in rust color with laser guns and claws (mandibles), charging at humans.
2- I can make general human population of 16 and dress them generically.
3- We can place humans on upper side of the slope/mountain because they will be looking down at ants.
4- I can depict a crazy sci-fi scene by explosions, snow erupting, grey skies and black clouds.
5- In short, I will put life, sensation and character in the scene.
Also I really like your idea, very impressive.
Thanks for reading, I look forward to design this artwork.
