Darth Doom... sounds good to me - at least it's better than Dr Vader!
I try to always come up with original ideas - and I thought I'd done it again with 'Darth Doom'... until I Googled the name and found out I'm certainly not the first person to think it would be a good idea to mix these two legendary bad guys. Nevertheless, I really liked the concept and had ideas for how I wanted this character to look - so I went ahead and created my own version mixing elements of both characters' costumes.
This is a low-res version of the original which was drawn in Photoshop using a Wacom pad.
