Watercolour Painting- Nature

I love watercolour painting as it gives a dreamy and translucent effect. Finally I started to practise watercolour painting today. I'm not very happy with the colour of the trees scenery and cactus. I have to practise more to get the colour right and dreamy effects.  

Update

I was not very happy with earlier work so today I painted again to improve the painting. Does it look better now?
