You seem to like humour/ecchi/harem quite a bit
In your first post you said you liked elfen lied, so if you feel like giving something darker a go - try
Higurashi no Naku Koro ni
Da Capo Should be fine if you liked Shuffle.
A good drama/romance is definitely
Canvas 2 - tho without magic stuff.
If you have nothing against ongoing series you can try
Happiness! and
Gift - Eternal Rainbow
