Tineye reverse image search brought me to a 404 page but the overall deviantart gallery is still up and clearly matches the style of the redraw: https://www.deviantart.com/draknairy/gallery

The original artist's portfolio site has it filed under "concept art": http://guro.com.ua/concept/2, and there are two more images that seem to be from the same series, showing a young woman with a raygun who appears to be the main character and some enemy designs. (The latter doesn't show up in the grid view but it's there if you click the dragon and navigate to the right). That's all I can find.
