Hello, Ririx, thank you for your feedback. I like to see this project like a school, where I can learn with other artists and pratice to get better, sure that will be a challenge sometimes, but this is the better way to improvement. So sorry, but at moment I like to dare this challenge by myself, but thanks for offering your help. I'll remember you suggestions next time. See you 
Also, I'll visit your page too, very soon.
