This is unfinish but can you guys tell me what you think? and like give me advice how to make it better. this is for an art competition XD. The Image is just your imagination of a lady O_O.

It's a very creative piece. I like your use of colors. I would define the chin and jaw a bit more. As well, to fill up space at the bottom, I would extend the red "ribbon" (what exactly are they supposed to be, if anything? ) and have multiple ones to make some sort of design. Great job. Post another photo of the finished piece. :)

Hey, this is looking great so far!
I would add more color, but don't go overboard. I like how your attention is first caught on her eye and the colors around it. That is a nice focal point, keep it like that. I agree with Mona on extending the red ribbon and defining her chin and jawline.

Maybe having flowing movements and lines, more ribbons if you like, at the bottom where the white space is. I think it would be nice to keep the eye moving for this piece. Perhaps accent her eyelashes a bit more, and blend.

=) Awesome job!

it`s really nice, i love the color schemes.
i would add a neck. it just looks like a
floating head.
nice job ! i loove it.

Woah, I love the colors. Very nice. Pretty too. I'm sure you'll win

Like mona said, define the chin and stuff. But I think you said you weren't done.
