try some tuts on how to blend it better in. Altough the last one is the best the first is more unique. Try to work on color
i'd say cut down on the c4d usage, it currently just adds a uniform texture across your sigs instead of emphasizing the flow. ;0
yea, the first and 3rd look pretty chaotic with the effects. last is best but like they said, but slightly overblended. kiu!
