I'm happy you like it! blending modes are amazing, it's just about test and test and test. Sometimes I simply put a rectangle with a colored gradient above a character and play with blend modes to see how it react on render, you can get very nice effects just testing! (remember you can mask the rectangle, if you don't want to scape from the character limits)
This is really a cool feature I have to go deeper, sometimes I tryed randomly blending modes without knowing its use, always obtaining black shapes

. I don't remember now if I missed to read something in the guide, but I really wasn't aware of how to use it so I decided to leave it for the future. I have to learn how to use masking feature too. I didn't understand well how it works, but I saw there's a huge explaining thread

, anyway I want to try one thing at time for a better understanding. Thank you again!
Uolter, sometimes the client's ideas don't make for good design.
I agree with you neeter (hey, saw your cover arts...very beautiful!), this is more a simple drawing than a logo. I know logos are different, I did some when I was in academy. I remember something like this (this is a quick sketch):

Recently I did the one I use as avatar even if It not conviced me so much.
Truth is I'm not very good with this stuff, my teacher always said that I was for workshop signs instead..."but no one need them now!"
I'm doing this just for fun and because they're friends, and I will not get any money. Initially I was asked to make a simple flyer with a cartoon drawing, but later they asked me to make something with this kind of dice. This is what came out...maybe a real graphic designer can do it more better, but I spent most of my life in expressionist paintings or pastel drawings (I love Degas)so this is the best I can do...
However that, I've been involved in music scene for about 15 years, lot of bands don't like logos and prefer drawings, like hardcore bands often choose old school tattoes style(which I like very much)...well I think I'm going nowhere now, so I quit, but I am so excited I came back drawing so I like to talk about whenever I can...thanks for your kind comment!
