Thanks to all! Well, this is finished, but in the future I wold like to make some more things, so I called this a wip. Sorry for that.

@madPXL: Its the same palette but the ideia isnt from there. 

good black lining.

Do you used this as reference for the carot shooter? :

so good idea for vegetables against bad food ( I have this idea since a long time but you did it first...)

Nice idea!  The top of the water jug should be a straight line or at maximum a
bend downward curve.
Does the carrot shoot pees?
Great idea on the flying hotdogs! Please animate them !!!!!

I believe that Zccc was referring to the status of the SHMUP. Given that the piece does not appear to be in need of additional backgrounds and/or enemies.

I like the fridge. Real stylish decor.

Looks tasty!
Way better than your previous pics, keep the quality! This pic is great.
