Meegannie, I really don't think you should be worrying yourself too much. Some parts of me tell me to hold back in statements like the above because this is a web forum after all, and maybe its not possible to make assumptions however complimentary..other parts tell me that a lot of the time people show more of themselves in this environment than they do in real life. I have to second what Miss Flower says about you..you have a superb sense of humour, and articulate yourself in so many great ways from what I've read here for however many months..
The best piece of advice I was given was that you can never over-sell yourself..don't hold back for fear of displaying a blossoming ego..flaunt everything you can..and secondly make sure you can talk about it when you travel over for the interview so the experience is as comfortable as possible...I'm sure you can find a perfect line between the two..
You've probably seen a million of these but just in case a few new points crop up its worth seeing, especially for the example statements which may give you some ideas to incorporate into your own while looking at the critical notes in brackets displaying each statement's strengths and weaknesses..this is the website..
