Taken from his site (http://www.yigitkoroglu.com): "I am an artist from Turkey. After graduating Mimar Sinan Fine Arts University, somehow i found myself in the world of concept art and illustration. I have been working for various companies and individuals since 2009. I am always looking for new and interesting projects to work in as a freelancer."
Amongst other things, his art has been featured in the Star Wars LCG (The Search for Skywalker) and the Lord of the Rings LCG (The Morgul Vale). Examples of both can be found on his deviantart page: http://yigitkoroglu.deviantart.com.
