Lately I have been working on learning some pixel art or pixel graphics. I have been doing this on an iPad app after uploading photos to it and later fixing the colors and overall look up with my own pixel dots I add in.
I actually published an article on Forbes lately with all of the graphic design and writing being my own and edited entirely by me. The topic was AI and natural language processing focusing on a company called OpenAI's efforts. You can read it here. The art below is my further implementations of what I added to the article originally and have been modifying since.
Here is my Metroid implementations of a piece I previously hand drew with pastels and I ran it through the pixel maker app and later back into Illustrator for the Mosaics effect.
