u/Aatrox_my_life

I am new in sound design and spent a lot of time watching different guides on youtube for last 2-3 months. But did not do any job by myself yet. I worked with my guitar tone and tried a few editing ideas, but not much more than that.
Now i want to try doing something. I want to redesign some scenes from somewhere, but i don't have a lot of ideas, what should i pick to try my skills, what scenes to redesign?
Also will be very thanksfull if someone can give some advices and tips in general. Sorry for not very clever question and my English, it's my 2nd language.
