This painting is of course inspired by Gandalf's fight against the Balrog on the bridge over Khazad Dûm. This painting was made as one of my applications for the gsCEPT programme of computer graphics at Luleå Tekniska Universitet. Estimated time I work on it is... at least 20 hours... I'm not very fast I guess. The .psd source file is so big it almost killed my computer working with it: somewhere around 5000x7000 px 16 bit per channel CMYK, with quite a few layers.
