I'm sure he's a very nice person, but since he's a stranger to me... I can't really say whether I like Wayne Reynolds or not.
His artwork, however? It's really hit and miss for me. By and large I like most of his depictions of monstrous beings. His style seems to suit inhuman/exaggerated physical characteristics more than it does for baseline human(oid)s.
That being said, I've liked a number of his human pictures. Every single one of the ones I've liked are ones where the characters are not in motion and/or screaming*. I don't really know what it is about it that turns me off of the action poses in his images, but it really does. I've never been a fan of "graargh!" imagery though, so maybe it shouldn't be so surprising.
The last thing that turns me off is this: over used. I like variety, so I don't like seeing too much of any one artist.
Anyhow, it's obvious that WAR is talented, and steadily improving in his craft. Unfortunately, it's generally not my cup of tea.
*One of my favourites was a black a white image in Defenders of the Faith where a priestess is giving a labourer some water. The character is smiling (not a smirk, not smiling and frowning at the same time, not smiling and trying to look bad-ass), as is the labourer. It's really nicely composed.
