I love the sunsets. I love to photograph sunsets. it.

I love to watch and enjoy sunsets. I think thak iIt's my favorite hour of the day of the in nature. There is no better color palette than the one sunsets show us- that it shows us, flashing and passionate colors which fade away until it gets completely dark. get attenuate in warm still to fade its in the dark of night.

At last, having a camera in hand, usually of my phone, so typical of everyone all people currently, capturing a picture of that beautiful moment in from nature and sharing it with friends is nice and relaxing.

So.. Shoot your moment

Great job! I also love taking pictures of sunsets! Best moment of the day!

I would say your last paragraph ('At last..) differently.  Try building simple and clear sentences.  For example:

'I always have my cell phone camera at hand ready to capture a beautiful moment.  Sharing my photos with friends is the best part of picture taking.'

Not sure if that's the meaning you tried to convey, but I would have said something like that.  

Again, good job and keep going!

Unexpected Gifts

Last week, one of my best friends told me that she wanted to attend a concert of a French singer named ZAZ. I told her that I would not be able to go with her to this concert because I've been trying to save as much money as I can. She told me that she would me invite me and give me the ticket. So, I saved about 60 USD.
Yesterday, a Canadian friend who used to live in Bogota texted me and told me that he's going to come to Bogota next week and he wants to attend a festival called "Stereo Picnic". I told him that the tickets for that festival are pretty expensive and that I wanted to attend one of the concerts, especially the one where Kings of Leon will perform, but that money is tight nowadays and I need to tighten my belt. So, he told me that he is going to give me the ticket, so that I can go with him and his friends to the concert. That day, another band I like a lot will perform as well, the name of the band is Kasabian. Aditionally, a Colombian band I like a lot since I was a child will perform too, they are Aterciopelados. I highly recommend their songs for those who want to know more about the Spanish spoken in Bogota.
It was a weird week. I rarely get stuff for free. The only things I easily get for free are problems. Finally, I will be able to see Kings of Leon perform in Bogota. I didn't attend the concert of Foo Fighters in Bogota and I still regret it.

This is perfect Camilo! A couple of small stylistic corrections.  I put '-' instead of ','.  You could also use ';' in both sentences where you name the band.  Otherwise-- great job! No mistakes :-)
