Building basic photoshop assignments

I need 3 photoshop assignments. Two photoshop assignment using magnetic lasso, fusion masking, merging at-least two images via layer masks, clipping mask and usage of brush. And one photoshop assignment using feather tool, automatic routing, disappearance, fluidity, filter gallery using trees, flames. I need a .psd file and photoshop default file format. It should not be copied from google and should be unique. We can consult on the images to be used for this assignment.
