What an awesome question!
In Our Shadow is inspired by a few things.
I am a huge fan of Macross (or Robotech) and my favourite thing about it is how it combines enormous scale battles and stakes, while still making the relationships and actions of a select few incredibly important without being contrived.
With my comic I wanted incredibly powerful foes that aren't particularly 'bad' but just following the way of life they are genetically predisposed to lead, and a concept that will be able to break that status and set the world right.
I was also heavily inspired by the visual style of pokemon, having drawn a lot of pokemon comics, mainly in the way animals are drawn. Translating that style to real world animals makes for a fairly interesting look, I think.
And of course, what character interactions in stories are complete without a little real life experience thrown in!
