Hi Koati, to me the cast is still visible elsewhere on the picture. Removing a cast from the whole picture is best achieved by using a white balance adjustment layer where one can set a white point in the image and it will adjust the colour balance of the complete image. You can try clicking in the yellowish bottom of your picture and see if you like the result. If not, delete the layer and try again by clicking in a different yellow spot (darker or lighter) and eventually you'll find the perfect spot. Hope it helps.
