Lee Sin's Splash Update - "Buttisface"

I appreciate what you were trying to do. The overall art is a vast improvement. The only thing about it I would consider worse is the face. Unfortunately, the face is the most important part of the splash art; it's what creates the in game icons, which cannot be covered by skins. A bad face can ruin the entire splash art, and I believe that's the case here.
Lee Sin's new icon is even rotated and modified (his chest isn't covering his chin) in a way that accents just how bad his face really is. The trapezoidal jaw is especially unsightly. His new face doesn't resemble the original character at all. It doesn't match any of his skins, and he looks like he has aged considerably.
Lee Sin is my favorite champion. He's the reason I started playing League of Legends in the first place. And it really saddens me that I cannot bare to look at his icon anymore.
I don't like to complain about work that obviously took a lot of time and skill to create, but I figured these boards exist for a reason, so I may as well offer my honest opinion. It's my hope that the new Lee Sin splash art remains the same with just a brand new face; one that creates an icon I enjoy staring at all game.
