Character: exobiologist

Here a doodle i worked on today. It took an hour. I tried to shade it using markers but i suck at markers... Lost some of the image i think..

Advice on marker technique is greatly appreciated.

The scanner is broken so i used a camera.

I think you need more contradistinction between the light and
the shadows
