Mostafa Abd ELsattar shared a really cool project on his Behance profile where he teaches with an Illustrator tutorial video how he created some incredible illustration of birds and patterns. It's not conventional illustration, it's a very abstract sand colorful set of artworks. I was definitely learned a lot from the video and that's the reason I decided to post here on Abduzeedo. You probably still remember that we used to post a lot of tutorials on the site. We moved a bit away from that because we thought they were getting a bit too repetitive but by looking at Mostafa's work I am 100% sure that I was completely wrong.
Check out the illustrations first and in the end you can see the Illustrator tutorial video. Also make sure to check Mostafa's work. He is a self-taught illustrator and Graphic Designer, who spend most of his time learning and experimenting new stuff in the digital art field.
