Clear vocals (which are visibly more 'in front').
Smooth guitars, lack rapid fret-shredding (what tries to fake it, in last song's refrain, is just chaotic guitar-f**k), melodies are well-arranged and played. What has to come 'in front', comes out when it has to, etc.
Everything just lacks some spontaneous shreds here and there, but having this exalted mood, looong solos and all, it's really great!
