This is one of the pixel art I most wanted to do recently, it's certainly not the best work I've ever done, but the important thing is that I tried to do something cool.
I tried to make a small pixel art of my beloved Hugh Jackman AKA Wolverine; one of the men I most admire and love in this world!

I tried to recreate his face with pixels using an array of order close to 50, but as you can see some detail of the face I couldn't draw because of the low amount of pixels on the screen.
Unfortunately I don't have the ability to work with arrays above the order of 80 because there are many dots and many variations of color tones that are too close to compose shadows and points of light in the drawing.
I tried to improvise working with a smaller array, but the eyes and lips were getting sharp, especially the eyes.

Anyway, I hope you can enjoy this little art!

I used the PISKEL application which is a free platform for creating sprites and pixel art for both amateur and professional artists!
