This is just my opinion on the art, but I really don't like Vandal Brand's facial expression and the general vibe that his new splash art gives.
Just take a look at the old one to see what I'm talking about.
It looks like you've just randomly walked into a bar and you're going to get your ass beaten because you've shown yourself in the wrong place at the wrong time. Vandal Brand is furious, his eyes are angrily staring at you while the burst of flames from his left hand is melting his glass. He looks like someone you don't want to mess with, he is **intimidating**. His posture conveys the message even more, since it lets you observe the spikes and the menacing symbol on the rear of his jacket. Lastly, on the top left side of the splash art, you can see a keg of Graggy Ice, which reminds you of Vandal Gragas.
The new splash art, instead, is just Vandal Brand chilling and laughing for no apparent reason. There's no intimidation, no reference to other Vandal skins and absolutely no message.
So please, if you want to update Vandal Brand's splash art, learn something from the artists that have worked on it and improve it, instead of taking away the only cool things that made it original and unique.
