I'd like to share this excellent find. Todd McFarlane is pretty much one of the many comic book artists in the 90s that re-defined and invigorated the comic book industry and simply put the artistry of comic books to another level. He has posted a bunch of videos giving tips on how he draws and create in Photoshop, and they are a good starting point to anyone wanting to transition from traditional to digital.
[And] when I draw the character [Superman], I put the 'S' on last, because that's the thing that defines him and empowers him. Without it, he's just another superhero with a cape. But when you put the 'S' symbol on, it raises him to an iconic level.
Have you ever been asked to draw a character whose costume is filled with beads and pearls? Do you dread the thought of drawing all those small circles one by one? Then this Photoshop trick is for you.
