Yes it's very 90s but for various reasons that early 90s X-Men run is a defining one in my mind. Admittedly I actually prefered it when Cyclops was with Emma Frost, but thats another matter. And the less said about the current version of Cyclops the better probably.
Anyway the point is that the artist did a really good job of capturing the style and feel of the characters back then.
