I haven't read comics in a while, so this will be a mix of dudes I dug in the '90s through about five years ago maybe? And only from books I've actually read. So yeah, I like Mike Allred (X-Force/X-Statix, Madman), Ed McGuinness (Deadpool), Clayton Henry (Alpha Flight), Jim Calafiore (Deadpool, Exiles), Steve McNiven (Civil War), John Romita Jr (Spider-man) and Joe Madureira (X-Men).
And probably a bunch more.
Edit- And I really liked Darick Robertson's work, especially on the Rucka penned Wolverine relaunch. I loved how he drew him short, ugly and mean.
