Took some advice I learned from the last (unfactual) thread, tried it in an actual (factual) attempt. What's the damage?
You should try starting with a simple, basic render or stock that can be easily managed and look good in a sig. Even I would have difficulty with an overcomplicated wireframe render such as that. I suggest you start small, as we all did (dont make me take out the abomination that was my first sig) and just choose a common render and try some effects and C4Ds. I also suggest looking at some tutorials to get ideas for your sigs. If you need any help or ideas just PM me.
