A few questions:
1) What level are you starting at? If you're starting at level 1, I'm not sure how fun it will be for the first 5 or 6 levels.
2) Is the misspelling of "Martial Rouge" intentional in this case? 
3) Is that Ardent Dilettante 4? If so, what are you getting out of it that you find preferable to more Bard?
1. I'm well aware that in combat she's gonna be limited for a few levels, her role in those cases would basically be the party face keeping them out of trouble...the skill monkey as it were
2. I do that all the time im sorry
3. Nice flavor, More durability, Bonus feat, and skills that scale off charisma
See no matter what i do I'm going heartwarder from levels 11-20
The difficult part is finalizing what comes before it. Plus it's the only Prestige class for bards I could find, that doesn't require me to have level 3 spells to get into......actually now that I think about it if I'm doing it like this it would be easy for me to qualify for lyric thaumaturge....though now I have to rethink what my lvl 9 feat would be cause extend spell is useless to me with out the faerie enchantment feat
Also I wanna make a few changes I've been stringing about
Bard 1
Battle Dancer 1(replacing the martial Rouge 2 levels)
Bard 4(Adding one more Bard level for good measure)
Lyric Thaumaturege 4
Heartwarder 10
Melodic Casting
Dodge
Spell Focus(Enchantment)
Mobility
Snowflake Wardance
No idea what to get for Level 9
Elusive Target
No idea what to get for Level 15
Versatile Spellcaster
And some spell changes that I don't think are worth getting into.
The general idea is to basically make a character as SAD as possible,and having heartwarder amplify all of that.
