I have, yet i won't be sharing it. Took a lot of time to arrive at it

Which should not at all deter you, though. You should fiddle around with the lighting setting and the res setting (i use 800-1000 render samples, but even 500 will do in most cases for isometric).
For lighting i use a simple lamp, set to contrast/brightness, with brightness=0, contrast (usually) 18.0 and strength at around 4.0.
Obviously always use Cycles render!
