Hello Luis and welcome to CiC.
I think you are correct when you say that what really can make a difference is lots of practice. Study the work of others photographers whose pictures you admire. Ask yourself what it is they have done to make the picture so attractive. Ask lots of question of other people on here. I would hope they will always provide a helpful response.
So that you don't continue to get people asking you what your proper name is, because most us use that on here, you can go to Edit Profile and enter your proper name under 'Real Name'. Then it will appear underneath your Username in all your posts. You can also enter your location so that it does the same, just as in my details alongside this message. Then we all know where everyone is in the world.
