While I respect Sweet's skill, and I think he'd be great at drawing the Shadowfell or equivalent, his art looks extreeeeemely muddy, like it was painted with clay, and that has limited applications outside of gloom-oriented scenes.
Check out his New tab, he has pieces there with brighter palettes.
e.g.
New, New, New, New, New
I really like his style because it feels like a great cross between modern and classic fantasy art, which I think would be perfect for D&D Next.
Although I'd be happy if he just did the covers. His style is a little intense.
Inside, I would like to see more variety, and some weirdness and whimsy. That's a nice "palette cleanser" between uberawesome heroic fantasy spreads. If it's all dramatic action all the time, it kind of wears on you and approaches an uncanny valley-like effect where it's just weird how seriously the artist is taking something that is inherently silly.

It's like...you're taking the idea of sharks swimming in sand a little too seriously here.
