happy to do a cover illustration for The Coding Samurai

I am very happy and honored to create a cover illustration for my friend Ian. his new sci-fi book just released at amazon. haven't read the story yet, but the book got a lot of positive comments at amazon. if you are interested in purchase one , here is the online link for it.
I made two versions: warm tone and cold tone. and the book ended up with the cold one. really excited to get the physical paper book!!
