I dont see the relation to data core, unless I dont remeber datacore... it was the one with the trip mines near the desk?

It looks good, but I do agree strongly with lep, it needs some variation.

I think this would work better if it was part-laboratory (some bits are obviously inspired by the SP levels), that way it wouldn't be just another crate warehouse!

Those arches should be made curvier, you can clearly see where the
brushes begin and end. Also, think about breaking up the texture
on the walls, I don't like the way the texture repitition looks.

Yea I have to change many parts of datacore to get a new style. The
room with the shelves is a room with a big column in the middle @
HLDM's datacore. I had no idea how to re-design this room, so I created
this one - well which is not finished yet.

The door on the right in the second pic down could have a bent/broken look?

Ok I can see the similarity between the datacore dead-end bit and your
map now (though you have gone for a far larger scale), but the new area
with the shelves now leaves me baffled as to what area its based on
Its all looking nice though, keep up the good work :smile:

Well this room is based on these two screenshots:
My idea: Using the basic architecture of this room: http://bs-army.com/members/ding/maps/honey/datacore0009.jpg
and then using the style of this one:

(I have never seen an alpha of HL2 tbh )

Me like

This is the lab room without the lab props, taken from the alpha... or at least you've done a remake of it... but you can't fool me!
