First off, I think the title is perfect.
She does give off that friendly and heart-warming aura, with the smile, face and body position.

But I like the background more. It looks to me like a "poorly conditioned film" effect.
And the font of the title matches the scene. Maybe some form of 'fancy' joined-up font may give it an equally good presence, but may make it look 'older' like most poorly conditioned films. (You know, the typical Black and White silent shows with text/quotes for each scene.)

Finally... it's purple. VERY NICE COLOUR! Great Wallpaper Aiyume.

Tip for the neck: I usually do my male's necks by making it's thickness about 1/2 a chin's length in each direction.
E.g. if a (whole) chin was 8cm, find the centre of it. Then mark 2cms from the centre to both left and right of centre, and draw a lines for the neck.
A females one is slightly thinner, but not by much.

I would advice getting some "How to Draw Manga" books, if you not already have some. I learnt everything from them.

Apart from that, it's a very nice 1st pic. Yes, I too like the hair... mine's all clumps of hair, rather than a collection of little strands. A very pretty girl.
