Started to create the wedding cake. Lots of warping, perspective and distort to make it match the initial cakes layers. Masking between top pizzas and thick edges.
Selected all roses using the quick selection tool, changed color to red, duplicated roses layer, desaturated and changed blending mode to overlay. Also played with brightness and contrast and lower opacity down just a touch.
Changed color of the plates and stand to red. Added shadows to it and to the roses as well.
Using the rule tool I have corrected the wedding cake position as it was a little bit out of the vertical in the initial photo.
Added glitter backround, some shadows and lights using gradients.
