I used maya to models simple leaf and Maya Xgen for hair, Zbrush for detail sculpt and substance painter for texturing.
Model's unwrap and NM was baked in Zbrush and other details like- curvature, depth, AO and cavity was baked in Substance painter.
For detailed renders please take a look at my artstation page:- https://www.artstation.com/artwork/Z5wvz8
