Poster - Happy Birthday III

So...she must like stars clouds, trees, and fire. Could you explain a little more about the elements you used? Right now I think you could improve the composition a little more. Everything feels a little misplaced and unstructured.

I like better the last poster you did for your other friends; the poster with circles and vintage colors.

There is nothing really bad about this design but it just has a lack of interest. The way you have the stars also makes me feel like I'm suppose to get more out of it then I really am. I think you need to make the much more interesting.

I think is need more action. Like are the stars falling more depth maybe, or making the background a sky or something to draw it all together.

i would go with a white or black background. the yellowy green is unsettling. how big are you printing this out? how old is she? i used to like posters when i was younger, but now i enjoy smaller things to decorate my walls. take her decoration style into account. certainly better than a store bought birthday card, but this doesn't get you out of baking cake or buying presents~!

the blur/circle effect on top of the stars - at first glance it seemed kinda cool but after few seconds its a tiny bit strange to me.

I would maybe increase the message to her which I think is in the top right, maybe throw it in the middle of the card in huge letters on like three lines with a "handwritten" style font maybe with a pencil/crayon type texture?
