Okay, done with my judging now.
Map 1 - Parkball - Hillis
Originality : 5
# A bit like space, but a much bigger one. Adds some twist to that, but other than that there's not much new stuff here.
Gameplay : 5
# -1p, goals too small
# -2p, i don't know which side is blue, which red
# -2p, slightly boring. It's just flat surface where most of the gameplay takes place.
Eyecandy : 3
# -1p, skybox and ground don't go together
# -1p, water fails (this is plus for gameplay though, i think)
# -2p, trees are a bit ugly, map consists of a flying grass box
# -2p, feels too empty
# -1p, caulk used under the map
Overall : 5
Map 2 - Ballz - Cortez
Originality : 3
# duodecuple, with a *little* twist...
Gameplay : 2
# wtf, lag
Eyecandy : 4
# okay, but it's almost like duodecuple
Overall : 2
# would be awesome if it didn't lag up the place
# nexball was not designed for 336 balls
# Was a good rofl though. (although you asked how many balls nexball can take, I didn't expect THIS many)
Map 3 - No Arena - Ai
Originality : 9
Gameplay : 3
# hard to score, goal triggers are in the air
# can fall thru lava and walk around under the map
Eyecandy : 7
# -2p, I see caulk, in the game!
# -1p, Vis culling problems
Overall : 4 # in it's current state, it seems like a hard map because of thee invisible goals
Map 4 - CB Nexball - C. Brutail
Originality : 10! Haven't seen anything like this yet and am loving the idea!
Gameplay : 3
# -3p both goals are ball_redgoal!
# -2p too easy to score right from the spawnpoint
# -1p hard to see who has the ball (bright skybox)
# -1p, goal trigger should be thicker (ball sometimes goes right through...)
Eyecandy : 9
# terrain texture looks tiling, -1p (could fix that with some terrain blending i think

)
# trees float in midair
Overall : 4, quite unplayable because of both goals are ball_redgoal...
Map 5 - Second Stage - TVR
Originality : 6
# as you said, needs a glass to force players to take the ramps, then it'll be much more original! (9)
Gameplay : 7
# red/blue goals are flipped, the and a bit too tall.
Eyecandy : 4
# missing texture! Also, map should have some kind of visible edges
Overall : 7
# add some glass to make it even more interesting
Map 6 - Rock 'n Ball - morphed
Originality : 7 # Basketball has already been implemented, but the terrain adds an interesting twist to the game
Gameplay : 2
# -3p Baskets should be bigger, it's close to impossible to score.
# -1p It should be more obvious that you cant score from under the basket.
# -2p Sides should be clipped with weaponclip (right now it goes right through, under the map).
# -2p There should be a trigger_push on the basket to prevent a player from camping there, making it impossible to score!
Eyecandy : 9 # -1p splotches and texture scale is tiny (both probably q3map2 bugs?)
Overall : 3 # without these bugs it would have been a 9 or 10!
Map 7 - Bubble Ball - Ronan
Originality : 7
# Hmm, a turret. Interesting... First nexball map with a turret
# invisible jumppads that throw you into trigger_hurt? original but evil!
Gameplay : 5
# -3p, invisible push triggers that send you to your death!? Now that's evil!
# turret is evil!
# -2p, no colors on the goals
Eyecandy : 4
# missing textures, clearly see tiling effects on textures, lacks detail
Overall : 6
# you cauld make the darn moles visible
