I really thank you all for your answers, and your advices. It really help me to understand how to do better the next time.
And, above all, know you liked it helps me to relax because I was very very very nervous, anxious... and all you can imagine about posting it.
Elena, It's possible to change the file after it have been posted ? Because, if it's possible, I will change the title cards and repost it very soon. And maybe this time, it will be no problems of weird colors.
And thanks, Elena, for making the realvideo version.
