They are great Rob.
I have done quite a few like this myself, in the past. Your spring is a couple of weeks behind ours, by the look of it. My favourite time is yet to come to you, where there are developing leaves on the twigs and they are still small enough to reveal a lot of the sky. Where you have different species in the canopy, the leaf sizes and densities differ, which adds another layer of complexity which can look wonderful.
