Custom Adobe Illustrator Brush Experiment II

I just noticed that I can set 'pressure' in the art brush I made from the last post (silly me)! 

Below:

I used a little pressure on the random sketch on the left, and a little more pressure on the right profile head (notice the chin). I think the wrinkles of the brush make the line look organic. It's fun and I don't have to worry about shaky lines coming from my shaky hand with this brush!! :D

Adobe Illustrator Brush Test

Ever since I started using Adobe Illustrator, I haven't really tried to use the brush sets because I always think that they look very fake. However, recently, because I want to submit some illustrations to a stock illustration site, and they need vector illustrations more, so I tried to see if I can achieve that hand-drawn feeling with AI.

Here's my first quick experiment with the Artistic_ChalkCharcoalPencil Brushes. I like the look of the 'Pencil thick' brush:

Applied it to the Noel illustration I drew with the Pen tool (P). 

Filled the illustration with color like usual.

With color on the background:

It's fun to use, but I'm not very satisfied with the outcome. I'll try to see if I can make a custom brush that can achieve what I want :)
