I'm gonna come out with it on this one.
To be honest, at first I despised your graphics, I really didn't like them and weren't getting much better for a while there.
But holy cow, this is such an amazing improvement, you've obviously discovered how to use C4D's which is really great.
One thing may I ask, is try this for me, let's just for a while, tone down the brushes a whole ton, infact try not using brushes at all, and concentrate on your C4D's, use effect C4D's as your new tool, erase bad parts that don't fit in them etc, but just get them into your repitua [no clue how to spell that], I had the same problem as you, I loved my brushes but I can assure you, all you really need are splatter brushes and smudge brushes, because everything else starts to look tacky after a while.
Just a few tips for you, you're doing great ;D
