People have been asking what kind of brushes I use on photoshop. The thing is, I use the brushes already provided by photoshop! Here’s a pic to show what I use:

These are all of the brushes I use the most. Yeah, there’s a lot of 36 brushes haah but as the pic details, they each have a different consistency. The top green 36 brush is the “mother” brush that I used to clone and tweak the other 36’s, including 10 and 7. 

I had made a brush tutorial on how to make a pencil brush a while back. If you’re interested, take a looky here. I am currently working with CS5 at the moment (I worked with cs4 when I wrote the guide) but there should be similar brushes that look like 36 in older photoshop programs.
