First of all hello to everybody, I'm new here

Second, sorry for my bad english

I would like to ask you, Derek, what are the staff you are using for drawing this gorgeous 2d graphics you are making for the game. Are you using a graphic tablet? Which one? And software? Photoshop, Gimp, Corel?
I'm also really interested in the steps you follow from the original sketch till the final image. Will be great some tutorial or video, any piece of advice or whatever. All will be really appreciated.
You are an inspiration for every illustrator!
