Insight to photoshop

In today's lesson we had an insight to PhotoShop.
I had demo showing me how to use the programme; I was taught how to edit and insert text as well as insert images. I learnt how to:

•  add background colours
•  text sizes and fonts 
• placing in images

When adding in my image of The Weeknd (Abel) I was shown how to maintain the images shape but make the image bigger or smaller. This is done by holding the 'Shift' button and dragging the points on the image.

My first document on PhotoShop is the one pictured below and basic tools have been used. I feel as though I will be able to get the hang of Adobe PhotoShop however it may take me some time to get used to.
