I picked up my copy today as well. After installing it I noticed two errors to be rectified - on the upper left edge of the plate there is a missing notch. This took all of five minutes to fix with a knife and file. Secondly, I noticed that the whole thing looked rather odd and lopsided, like the greeblie bay was positioned too far to the left. Consulting the reference photos of the real thing and double checking on the photos with compass dividers highlighted the problem - it appears that the plating on the right hand edge is too short - it should extend further to the left, covering more of the bay area space - by a millimetre or two. It can be fixed with plasticard, so that's on the to do list for the weekend.
If you want to check for yourselves, there is a really good picture on Maths's site showing a close up of this area. Use your dividers to compare the width of the armour plate on the bottom right of the bay area with the one on the left. On the real thing the with of the right one is slightly but noticeably wider than the one on the left. On th De Ago part they are more or less the same width.
