For a recent commission, I drew the power of Thundurus from the mystical reveal glass. It took quite a bit of effort and a hearty mix between vector art and pixel art. Though, getting the curves of the reveal glass right was a project by itself.
As an added bonus to my patrons on Patreon, I made downloads of the .psd and .ai files used to create this piece available for download and editing. (With the reveal glass free for commercial use.)
