When looking at your work I can tell that you certainly don't lack ideas. From where to you extract your inspiration; is it comics, old movies, life or something out of the box?
Going back to the old-school low poly characters that we all remember being so amazing has been my newest approach this year. When recreating Zero from Marvel vs Capcom (originally from the Rockman X series) I knew he would already have a great target audience. This way people can easily relate to the character, which is something I think about a lot before committing to anything. I wanted him to have a new twist, yet maintain that iconic original design that Capcom came up with. Thinking out of the box is a good way of putting it. As artists, it's important that we try to step away from what's already been seen and introduce things that are fresh and unique. Some inspiration comes from watching my childhood favorites: Laputa, Nausicaa, and many others. As for video games, the ones that had an impact on me when I was young were Final Fantasy VII to X, StarCraft, and Diablo II.
Modeling-wise, have you ever started your model from scratch, disregarding the current stage or development, due to having a new idea?
