Well . . . i started this soon after my first vector but suddenly lost interest in it because i dont know what to do.
I think it's :
- A bit empty or maybe lacks of colors
- Needs a background (but anything i put there seems not to fit)
- Lacks shades or maybe some light effects

It just isn't IT.

I'll be grateful for any tips on how to bust it up (Because i dont wanna just throw it away)

i find it very neatly done. and it looks to me so very much like modern/minimalist art, it's simply seductive as it is. the background's sweet blue contrasts with the scene, and that makes it even better. but if you really want to change it someway, change the background into a dark-grey/blood-red violently-splattered blend, that would change the mood quite a bit. i'm sure you know how to do the blend/background-layer

Thank you for your advice
I'm very grateful.
I'll try it as soon i i have the will to play with it again.
