hi! yes OFC! i would absolutely LOVE TO, thank you sm! some tips i would recommend when ideas aren't flowing into your head are:
1- try to visualize the scenario as if you were there in the moment
for example: lets say your character is in a park with lots of nature. try to visualize what the park would look like; whether it'd have trees with bright green leaves or tall grass with a river flowing by.
2- try to connect things/ideas with personification and metaphors, etc. to add subtle but sufficient details that draw people in
for example: if there's lots of thunder or it's raining a lot, you could say that the cloud was roaring profusely as though it had been insulted massively.
3- understand the character(s) personality and incorporate it into, again, figurative language. this, i believe, really makes the writing unique because everyone can portray something differently, but the way they portray that thing shapes a story. (PS. i don't recommend going overboard with the figurative language as it tends to confuse the readers and make the writing unclear)
overall, when writing the beginning, i recommend writing down the main conflict and THEN filling in the blanks. try to incorporate the beginning to that main conflict at the start of the story so the readers aren't like "hello when did this happen"
i hope this helped!
