How to use graphics software

Watch videos and look for inspiration, even if you copy something

You can find good tutorials on Youtube or Skillshare (get a few Free months).

it's hard in the beginning, but you will get used to shortcuts, and eventually it becomes second nature

following along tutorials are good for learning techniques, even if you don't really care too much about making that specific thing...just experimenting with the programs are probably the biggest way tho + consistency good luck
