Chiral compounds / Exam technique help

So when ever I have to draw two 3D optical isomers I seem to always not exactly recreate what the examiner has put in the mark scheme.
Despite knowing the theory behind it, and why chiral carbons exist etc.
So here's an example of a paper I've just done. image.jpg

Despite doing the correct mirror images the3d bonding was off from what the mark scheme put.
Is this correct or not?

The paper I've just done was Jan 2010, heres the mark scheme question 3bii http://www.ocr.org.uk/Images/63346-mark-scheme-january.pdf

Your answers are fine, you're just showing the carbons rotated to a different position shown on the MS. It is fine.
