Nice Tutorial. I just hate using C4Ds...but thats just me.
You don't HAVE to use C4Ds. if you want you can use brushes or renders for the same effect if you use the right ones. C4Ds are used to help with flow, color, or filler when this is too much solid space around in an area.
Some people hate using brushes that aren't part of the defaults as well, this is one that doesn't use custom brushes so you dont have to hunt for any I used as I only used the defaults
You can make,a whole sig without C4D or custom brushes, but soemtimes you will want them to help with flow, but with the right editing knowledge you can get a good effect with images. Though thta is the same as using C4Ds in its own way.
When using a C4d, you dont want to make it the central editing portion. some people just toss them in there as is, but they should be used to help flow the sig or add color and depth through erasing, styles, etc.
I used a couple of C4Ds here but I didn't toss in as is and leave them there. they look ugly without editing
