Title Screen: The melody really needs some space to breath and some new rhythms, like dotted rhythms or triplet rhythms - it’s all very on-the-beat and lacking any kind of momentum. The notes/harmonies are all kind of clustered in the same register; you might consider raising your strings to be higher up than the brass melody so that the melody stands out a bit more. As it is, the melody is difficult to distinguish (think What Lies At The End from FE15 for reference). It also needs a bass line, which could be accomplished by using timpani or bass guitar. The harp is making the harmonies a bit murky as well.
Valiant Remembrance: This one has some lovely textures and I love the close harmonies of the string section. You could again do with adding a stronger bass line in some of the repetitions so that the harmonic progression becomes clearer, but I think it’s quite nice as it is because it gives it a more ambient feel.
