I'm not at all offended or bothered by your questions. I believe that if I cannot explain why I judged an army a certain way, I should not be judging. I believe it is your right to ask these questions (assuming you're polite, which you have been so far), and that part of my responsibility in judging a major event like this is to answer these questions.
Not all judges feel this way - and that's fine. But I believe in accountability, so anyone else who I personally judged, feel free to contact me.
That said, 1) I don't have the sheets in front of me anymore. 2) I took pics of all the armies I judged, but they don't show a great level of detail, so while they might help jog my memory, they're not the same as having the models in front of me.
For the team tournament, the complete scoring criteria was:
(For each of the 4 armies in a coalition)
Paint:
1 point: Army was painted to a 3-color standard
1 point: Army was painted to more-than-three color standard
1 point: Army painting is uniform, not a mix of styles
1 point: Details were painted
2 points: Hand painted details were added, such as banners, unit markings, etc.
1 point: basic highlighting, "lines are neat, drybrushing is appropriate, inking is controlled and not sloppy".
2 points: Masterful highlighting - "Highlights have been masterfully blended, shaded, or layered.
2 Points: overall appearance is amazing, everything works great together to create an awesome scene.
Basing (choose 1):
1 point: models are based
2 points: models are really well based (extra stuff, details, painted on details, or so on.
Conversions (choose 1):
1 point: some weapon swaps
2 points: units have multi-kit conversions, including swaps
3 points: very difficult conversions using putty, plasticard, drilling, sawing, sculpting etc. Could also apply to the whole army having very well done multi-kit conversions.
After this, cap any individual army at 15 points (if you do the math above, there are more than 15 points to attain), so a coalition max is 60.
Like I said, I don't have your models in front of me to verify what I'm saying right now. From what I recall, you didn't have hand-painted details on the models, and they weren't what I'd call "expert blended".
The Overall appearance thing is really where judges award discretionary points. Kind of a way to indicate that this is one of the best looking overall armies on the day. I don't think your armies were among the best of the day, so that is why you didn't get those points.
So, you got the rest of the painting points.
Basing - I'm fairly certain your bases were just plain rocks. Correct me if I am wrong, but my photos seem to indicate this.
That leaves conversions, which seem to be what you keep bringing up.
The two armies, Tyranids and Guard, got the point for some minor swaps. I really didn't see anything extremely interesting in either of these, and while I'm sure that some of the guardsmen had weapons from other guard kits, that's still just a point.
The two other armies, the daemons, which, as you mentioned, had some fairly heavily converted crushers, and the orks, which had all sorts of chaos spawn parts, and nid claws on the killa kans, got the points for more interesting conversions. I don't think that they qualified for extremely difficult, or "very well done", which is what the 3-point category calls for.
I'm fairly sure that the horrors weren't converted much, nor the daemonettes or screamers. I could be wrong, and I'm not sure that if they had minor conversions, they would have bumped it up to that three point category either.
