Hi. Before i start, i wasn't asked to draw this. I wanted to give Artzy_Chan 's character, Scott a try. I drew him in my own style and it took me about 1hr and a half. I used Photoshop CC 2014.

This is the original Scott,

Here is my version of Artzy_Chan's, Scott. I'm not very good at youthful and i would call this an older version of him :). 

What I enjoy most about wanting to try her style is the colour. She goes crazy with her colours and it looks brilliant. I always wanted to be the artist who could make a messier planned artwork (but unfortunately i am not that artist). I also love her mangaka skills XD. 
So if you haven't, go check out Artzy_Chan's Art Book 1 and 2.

Enjoy!
