This is a design I did for one of the main characters of my personal project. It's going to be a comic once I got a solid enough amout of worldbuilding done. All the concept sketches I used Autodesk Sketchbook Pro, the final design started in Sketchbook too but I then moved it into Photoshop and finished it there.
I tried coming up with an outfit that shows that she works for the military but that is also adjustable and customizable for each faction member. Hilda is a bit of a rebel (which tends to cause herself some trouble), so it was important to have different options to make her stand out from her comrades without her looking completely out of place.
