Gustavo, I really like Flowers and Guitars. I don't think your attempt failed at all. It has a very diaphanous quality, like an very old painting that's faded with time, hazy and golden. The flowers are relatively clear while the guitars are almost ghosts in the background. I would frame and hang this.

Photo of the kids over Phoenix and the last ones of the weather are moody, expressing a sort of beautiful gloom.

I think you had an excellent week of photos!
