Lost my best friend recently; my computer.
You'll find I tend to draw things that can be considered recognizable. (Things from books/movies, certain animals...etc.) I feel that people tend to appreciate something more if they have a viable point to go off of when viewing it.
Doesn't mean I'll always do that though.
If you're wondering how I do it:
An iPad, and my index finger and thumb are what I use to draw. The only program I use is Procreate.
Though I also use these things called pencils when I can.
