Halo 4 exile forged (Halo Reach help)

So im working on a forged version of exile as we speak, for all intensive purposes ive been working on it for 4 hours.

So i have a question before i continue, Are theses 2 areas positioned corectly? I think i have the proportions backwards and i have very little to go off of.

Objects and items are not an issue. all i need to know is this
http://halo.xbox.com/en-us/haloreach/lordcrusnik1986/fileshare#?details=30550211 correct so far in terms of locations or do i have it completely backwards…it just doesnt seem correct

i think the angle off the rock isnt sharp enough but wait cause i dont build maps

it seems ok, but when i think about the layout, the broken ship overhang seems like it should be on the otherside because of the broken piece on the very top is angled differently then how i have the overhang.

i had to sleep, so ill be picking it back up in 30 or 40 minutes, before i do, does anyone know if its correct so far

im still not sure if this pic is accurate in placement and need some help.

when will this be done!!! i would love to play it
