Hey, I'm flattered to see you guys enjoyed my sketches.
A few answers to some comments I saw:
-This sketch ( the Samus one) was actually the first drawing I used a stylus with, which I got for Christmas. I've been playing around with it a lot, but make no mistake, up until around January I was using my fingers. It IS possible to draw with your fingers and it's honestly not that much easier with the stylus if you can get the technique down.
-I use the app Brushes because I find it to be the most intuitive. There are other programs that are great like Colors and Layers (Is there a theme to the names?) Layers has a bigger canvas, though I don't use it out of personal preferences even if it's probably the most versatile. There's Colors which I believe has stroke-by stroke playback and is also available for the NDS, if you have a flash card like an R4.
You can open up the files that Brushes creates in an OSX application and make a stroke by stroke playback video, so hopefully I can show some videos as well once I figure that out.
Also, would anybody be interested in a tutorial? I can write one really easily and I would be glad to drop some knowledge.
