mangaproductions

I was originally planning on turning this into a wall poster and selling it..

..but after seeing the final product.. i'm not so certain.

Mostly I feel as if i should have retraced my outline lines with a darker colour, making them mour defined.

If you would not mind, could you critique this peice for me?
And please, be as brutally honest as possible, highlighting both strong and weak points if any.

Thanks in advance ~

the background is very white

meeeh.. i dont like it.

could have been much better..
