Step-by-step: Capture the look of a futuristic glass helmet
1 From my concept sketch I create a round shape with a custom textured brush. I don’t want the glass to have an overly clean look, even if it’s usually a smooth polished surface. I use a neutral violet colour for this base. The glass shape and volume is only suggested by curved brush strokes and the rest of the helmet. 2 I refine the previous lines, and erase some dark parts inside the helmet leaving more room for my character. I try to create a clean, curved shape. I work the face as normal; I choose to keep the glass uncoloured, but you can quickly achieve coloured glass by adding colour on a low Opacity layer on top of the figure’s face. 3 To add light I paint some almost white curved lines on the borders of the glass part, where the glass is the most reflective. Adding some coloured hints of the surrounding environment will increase the realism of your helmet. With a very small Round brush I add small dots of light on the edges to bring in reflection effects.
