Did a little doodle using the Black Ink Program.. Then my trail ran out.. But I made my purchase right after because its a great program for concept ideas.. With the limiting tools it forces you to be more traditional which is awesome..
One great feature which would be an amazing addition to this program would be the ability to export PSD with Layers..
This program in combo with photoshop would be great.
Ill be using this program a lot for sketching out concepts and updating them on my blog..
