I have created a similar pond to yours. It has been very successful and I have frogs, toads and newts.
I have had a few problems therefore maybe a few tips for you to think about or look out for: topping up the pond with only rain water has been a challenge. I now have 3 water butts to help with this in summer. About 25% of the sides of my pond bleed into grass and other plants on the bank and although it looks really natural and is well used my birds and mammals for access to the pond it does absorb quite a lot of water.
Blanket weed has also been a problem - common to most ponds at one time or another. This year I have followed Monty's advice and stuffed a leg of a pair of tights with barley straw (50g per square metre of surface of the pond), secured the other leg under a stone at the edge of the pond under foliage and am letting it rot down. It seems to be doing its thing!
The only other thing I would say is if you know someone with a pond, approach them about having some plants. Pond plants can be expensive - I don't know why as they all grow at a terrific rate and need splitting, cut back or pulled out on a regular basis.
Hope this is useful to you. Good luck with your pond - make it as big as you can because once you start putting in plants and the edging grows - it seems that it shrinks!
