Well, I thought the kanji was clever: Instead of "I Trust You" it's "Ai Trust You". However, call me a loser, but I try to deny there is even a remote love-love relationship between these two. I mean, they deny it often enough in the anime. (I just hope it remains true!)

I like how you remain consistent with the color scheme, but if I didn't already know the title, the word "trust" would have been lost to me. Try to make the words stick out more. Also, the font itself is plain (for the English and the kanji).

StormFangs's suggestions are good; give Setsuna more reflection of his head there! =D

With the "trust you" title, I'm thinking you can implement some similar scene from the ending theme of the same title: add ripples of water at the bottom for the reflection or a nature scene in the background...?

Keep up the good work!
