Thanks buddy,
I am thinking about making the whole collection of games, all the games boxes I made have the same resolution (with a template for the Xbox logo header, Xbox Only games, Xbox Live+Only in Xbox label etc...) I also have an idea to include a transparent box in the fanart (same texture from the Confluence skin, the black/gray box with the games list) and make a template and include infos about the game (Developer, Publisher, Genre and Release date) I would place it in the top right corner on top of the game box,
By the way, I increased the resolution for TBNs in advancedsettings.xml to get a bigger thumbnail with a good resolution.
I will share this once achieved if anybody is interested... (It's really time consuming

)
