Character Creator 3 is for games and animation. If you want to do a Comic, stick to daz.
What I recommend is to to watch tutorials from the The WP Guru on YouTube to get you started.
There is a series to learn DAZ basics.
As for character morphs, don't overdo it. The more you have, the more heavy the whole program becomes.
Also, choose a generation of Genesis characters (we are currently on 8.1, but right now it might be a bit more advanced for you), so stick with Genesis 8 for the time being.
