The "platform" part is nice, though i think the curling bits coming out of the side might be a tad overkill. regarding the main block, that is exceedingly under detailled compared to say.. the "door".
what's the size comparison on that thing? i assume its meant to replace the temple? if so, i think you have quite a bit of room for detailling work there, and i highly suggest you implement that (not retarded detail work, something that'll make the model stand out/fit in. say, loads of areas for windows, placement for turrets, bay doors, cap ship docking moor, etc).
for 10% done, its looking to shape up nicely, but the end result depends on where you go with it.
I like the window, adds a surreal effect, which is great for the Phantoms IMO.
The rest... ehh. I'm not sure the idea of a space cathedral really works.
Or at least not in that way, where it looks like a cathedral's taken off from a planet to hang with all the guys in space.
Something more abstract would worker better, I think,
My two pieces of eight.
If it gets attached to an asteroid or some such, I'm sure it would look lovely. Well... With more detail on the actual cathedral building. But you said it was at 10%, so...
Anyways, if not, it'll just look like a floating box with a dock-y area.
Well I gotta say, it's perfect for the Phantoms... a a few years ago. The Phantoms are old fashioned, and I was hoping for a fresh boost, but this is more to the... whatever, I chose not to have a say in this anymore.
So I'll say it's a sexy model, and it'll look great with more detail and expansion.
