Bring digital art to cell phones?

Hi, I don't know how to put my drawing from my laptop on my phone WITHOUT the whole picture changing in color and size

Save the drawing in the desired image format.

Cable to the PC, mobile phone connected, allow data access, access the device in Explorer and move the file to the desired directory.

Or send yourself an email, attach the file and open the email on your smartphone.

Simply copy it to your Google Drive on your PC. Then you can pull it down on your cell phone.

I recommend installing this on your laptop: https://www.raidrive.com/ This can be used to set up Google Drive as the drive letter. Then it is most convenient.
