Gagea pen drawing

This is the first time for me to use this book, so I decided to choose an easy flower to start with.

This flower is called "Gagea", in the family Liliaceae.

The book has step-by-step guide to teach people how to draw a flower; first is to draw the outline using pencil. 

Then use a pen to draw the shape.

Erase those pencil marks.

Use pen to shade.

This book is great for beginners.
But I think I did not drew the right hand side flower bud very well.
Would need some more practice.
