I figure I should post this here in case people want to know what good scores look like.
Unoptimal scores I know of in this image (the parentheses are the score I got/have seen):
Because of @hygge 's post, I figure it's worth posting answers for top scores (these are "the highest i've seen", not the ones in image). Spoilers below. (It is both box count and the specific secret(s) that the score used, which is enough to trivially tie the solution for a lot of the levels.)

Thanks for the post! Got a lot of inspirations for improvements from your scores.
Also Lilly 2 (1680) and Turtle 2 (1360) are possible :D
Not sure if there are any other possible improvements
