Thank you for your comments guys. Yes, it was not meant to be an award winning composition, but just to show off the prowess that I have acquired in midi. No doubt I have only just started on the learning curve!
As for being Dutch, there are very strong linguistic links between Dutch and Afrikaans, and Oom does indeed mean uncle, but in Afrikaans the word is used in a very broad sense... anyone that looks a bit older than oneself is Oom, not just family.

Thank you for the encouragement.
