I don't think there's anything wrong with c4d's in tags. I like using them to spice up my tag or to get a desired effect.
C4D is easy wtf. All u got to do is get used to the program. Just google c4d mannal and it will have a adobe version of it to read so u know what all the buttons do.
it really does depend. For a long time I disliked c4d's because I couldnt use them...whenever I placed one in a tag it looked stupid. But they can lead to some really nice effects and I enjoy experimenting with them now. For LP's I honestly believe there is very little else as effective. I would say, for instance, most of the art I see in DA isn't as good as some LP c4d postwork. Of course there are exceptions (I do prefer photography) but I'm just saying that there at least c4d's really benefit.
i love using c4ds. it helps add flow and effects. if u know how to use them then it wont take away from the sig, it adds to it if u have seen my sigs i use c4ds in almost all of them.
lol,using other people's stocks is worse than c4d, since you didn't even create it in the first place. All you did was take a couple stocks, put them on lighten and bam, theres your tag. But with c4d, you need to already have some sort of a background first and manipulate them for it to fit in your sig.
