Female portrait drawing with mechanical pencils

Hello everyone, i am here to share a new pencil portrait drawing with you all. This is actually the same girl i shared the other day. I really liked how the first one turned out, specially the digital version. So i decided to do another one of her. This is now pencil drawing and later i will color this digitally. That should be fun.
What i love about these images are how the colors matches amazingly. The blue and white with the sky blue and white.
If i had done the background with those amazing sky and ice things, it would have been perfectly amazing.
I intend to do that for this one. But i am not sure if i will be able to. Not really very good at landscapes.

Enjoy and take a look at the process shots below:
