Hey guys,

What I really wanted to ask was if anybody knows how to shade in the Rockstar games style? I want to shade some sketches in Artrage on the iPad, but I'm a bit of a newbie when it comes to shading and don't really know where to start to get a certain look I'm after.

Here are a few examples of what I'm after:

Here are a few more by Hethe Srodawa in the same style:

If anybody has an idea what tools or settings I should use I'd really appreciate the help.

Many thanks,
