When you are creating a character for your own personal production, you can really minimize your time it takes for you to complete the character.
You don't have to create a multi view character, you can create a single angle character or just 2 angles if you prefer.
However understand that the other angles will still need to be populated in other for the character to use some of reallusions pre motions.
A single angle is pretty easy, because there is a button you can press that will instantly duplicate that one angle into all of the other views. They may look funny when you rotate the character, but it will allow the character to do pre motions more smoothly.
Now if you are going to be doing a lot of key framing and manual animation you will only need to create what's needed for just that scene. If you are only going to be using 3 eyes expression, don't waste your time creating 13. If you character is only going to walk across the scene then don't build out a full character with all of his facial expression. Do only what is needed to complete the animation. I would recommend you spend most of your time on your main characters that you will use over and over. You can also save time by recycling body parts such as Eye, Hands and Mouth expression.
Character creation can be very tedious and the learning curve is high in the beginning. You may want to start of by modifying existing G2 or G1 Characters before diving into creating your own.
Here is a quick video on how to create a single angle character in Crazytalk Animator.
