I don't really know who's inspiring me right now, but I'm so happy to find someone else who loves Darwyn Cooke's work! He's also a great writer too, and The New Frontier has some really amazing moments.
I guess lately I've been looking at Alex Ross a lot. I love his high detail painted style.
I've been trying to emulate it a bit, but it's ridiculous how good he is. It's worth mentioning that he often works with a penciller as well, but his painting style really brings things to life! I recommend checking out Marvels, Kingdom Come and Justice (which he co wrote and painted on pencils by Doug Braithwaite)
Also Chris Samnee is doing some absolutely stunning work on Daredevil lately. Really digging his stuff.
I really dislike the digital gradient a lot of modern comics use. Fortunately there's a bit of a revival of painted and poster style art.
