It is monotone but if you had this focal covered in vibrant colours and showy effects then it'd look tacky. The smoke effect works brilliantly - it is one of my favourite things at the moment because you can use it really easily once you have some experience using it. Blended very nicely. I like it but I think you could still get a few more subtle colours in that. Still, a great signature.

P.S. Corruption Runs thread needs a few more replies. Lol. :P
