enlighted vector

Hello all,
This is my second vector-artwork created in approximately 45 minuts.
It doesn't have a direct subject. I just created this because it came up in my mind.
So i was bored, designed something and this became the outcome

If you don't like it, or you disagree with something, please tell me what was made wrong,
what can i improve the next time? was the color-combination not that good?

feel free to respond on this one
Thanks in the future,

TrendWhored,
