Since you are starting out, find some simple projects to learn from. Find concepts from professional artists. Don't make your own when you are starting out. Concept art and Character Artist are two different jobs. You need to decide what you want to do. Tiles gave excellent advice. If you are going to just focus on character modeling practice character bust instead of trying to do a complete character. Then focus on modeling parts like say the ear, nose, hands. You need to model, UV then texture and see how it goes.
added an option for a look at constraint node for the projection direction for the conform.... the plane has a path constraint to a circle with a noise on the radius and conformed to the sphere.
