First, I do some general sketches, just to know where the main parts of the illustration will go.then, using my sketche as a base, I draw over it, making the art more clean and placing the details.

After creating all the shape of the drawing and checking if the anatomy is right, It's time to paint !I use two painting methods, in this one I used grayscale, where I paint all the shadows and lights first and then add the colors on top.

In the end I just add more details like highlights, textures, better lights and shadows, and this is the end result. ;)
