Scratch from the beginning

Now it's quite a bit I've start to paint with watercolors, and I have to say this makes me feel good.
I can actually see how I improve day by day and then I've decide to insert them on my personal web page: http://www.barbarisa.com/myart.html
I don't want to attend classes for the moment so I may need some feedbacks from expert painters around there, whoever is interested in helping me anyway.

So, let's start with my favourite painting: Terra di Siena.
I think I may want to paint ligher, I think there is too many layers in this painting.
I like the pink and green trees on the top, because they are light. I think I will try again.
