Hello there to Brazil! Your pencil drawings are amazing. I really like how you focus on simplicity in colors and use your pencils to bring out shadows and textures. I also draw and color with pencils, though I am nowhere this good. I really commend you keeping alive the traditional methods. I love the digital art, but I also love to see people support the hand-drawn stuff.
There is also a group out there called Done by Pencil that celebrates this type of art. You might consider placing your art there. More info here: [link]
