I think Ezreal needs the Maokai treatment concerning his visuals...
Ezreals model looks outdated and does not look like his splash art. You cannot really deny that when you look at this:

He looks like a 10 year old boy. Ezreal is not a 10 year old boy.... I think.
You don't even need to look at the model viewer to see that his model needs help. In game you will notice a lack animations when compared to all the newer champs. You will also notice (especially when put next to a support with a nice model) that his model is small and disproportionate. And when you zoom in more closely, you notice that his face looks like it has been plastered on, and the "war paint" on his cheeks look like scars. His hair also looks suspiciously like an exotic fruit....
His ability animations and icons are kind of outdated looking too. His q especially looks damn old. His e, w, and ulti are not THAT bad but they lack detail when compared to other newer abilities. His ulti looks pretty lame when compared to the other global ultis when it flies across the map. I think it should look a bit thicker and leave a bit of light distortion in its path, kind of like lux's ulti.
He has a great concept however, and his gameplay design is fine. Which is why I think he deserves to have the same treatment as Maokai, with his model and animations getting a bit of polishing. I am not demanding it now, but I wish it could happen sooner or later....
