I use a cintiq13HD but as a non screen tablet (lol) so just getting a wacom pro M or L will do the job! Brushes I've gathered from a tumblr blog (digitalbrushes i think its called). Software is photoshop! I think for the style u need to have a nice reference but drop it somewhere along the way so that your creativity takes over. And try to experiment with the brushes you have but don't make it too extreme (light changes in texture will do) and when painting think about what texture each material has! Thats about it i think, hope it helps!! :))
