Zbrush is an amzing thing, but the learning curve can take longer to do.

Start with something like Silo (others will recommend various free ones, test them out, nothing to loose) and do little things to start with. Simple tops, dresses, skirts etc.

Gain confidence in what you are doing and you will want to do more.

The amount of people I have seen that on their first go, they want to model a full hypersuit with helmet, boots etc. What normally happnes is, it doesn't go as well as they thought and then they give up.

Small steps, lead to bigger things.

All the best.
