please help me choose a thumbnail (Patreon)

Hello!! I'm uploading a quiet, ambient drawing video, and I'm really agonizing over the thumbnail -- I want to keep it simple but I fear that simple will be some kind of false advertisement. So I implore you to help me choose the base photo!

♡♥♡♥♡♥♡♥♡♥

1) wide desk shot

2) colorful sketchbook close-up

3) scan + desk shot

4) plain sketchbook close up

♡♥♡♥♡♥♡♥♡♥

I'm really leaning towards the wide desk shot, but again, I fear that it's too vague, and also my desk is so messy rip

let me know which one you think would be the most effective/clickable as a thumbnail, pls and thank you <3333

the video is already uploaded and it's gonna go public tomorrow but you guys will be seeing it tonight :o)
