The top of the line program
I have been sketching since I can remember, really, but not seriously until I was a teenager, says Aigie. I enjoy challenging myself with different perspectives and the process at which I got from point A to point B. This is why I use Artpad for most of my sketching. Sure, Entropiauniverse ped is not the top of the line program and it is free -- but it has a replay button, and you can see the logical process in which my work evolves.
