If I were you, id look up videos on thumbnail creation with programs like GIMP or Paint.Net, There's lots of videos on how to do so with a simple search.
Very informative and honestly sad. Ever since Microsoft took over, i have been missing the old style and charm they keep changing in the game. When they changed the textures i definitely started to realize they have full control and i fear that Minecraft may loose its touch to its roots. I left the community for a while and came back to realize all the music was different and it really did kinda upset me. Thanks for the documentation and information man. Take an emerald.
Dark Mode honestly looks more aesthetically pleasing to me, and also relieves my eyes from the piercing light at night. Sometimes for me reading in light mode helps with my eyes during the day, Then again, my eyes are about shot.
