Thank you, Maja for such informative class. 
I am sharing just the first part of my projects.
Enjoying it!

Added a Notebook collection. Not sure if the black background berries pattern looks good.

Added a Pillows collection. Love playing with background color adjustments.

The last part - the pictures and mocking them into mock-ups - took me more time but was worth it! 
I got white iPod case and my daughter’s white Vans. 
I experimented with the iPod and used a .png file over the picture, then just arranged it to a right position, using warping tool.
