My depressed monstera leaf

I got my first monstera recently. I put it in a new bigger pot right away, because it had started growing out of the bottom part of the old one. I haven't really watered it at all, been waiting for the soil to dry, but I have sprayed the leaves with water multiple times a day. It recently got its first new leaf, but it looks very sad and droopy. Does it look like this because it's new and will perk up or have I done something wrong? The other old leaves look fine. The new one is also possibly a lighter green than the others.
I hope someone might know what's up with my very loved plant :(

The leaf.

The rest looks fine, as you might see.

I think it will start looking happier with time! Generally the leaves start out a lighter green and darken over time. That goes for the thickness of the leaf too, it should get better with time.  Pretty plant! 

Thank you! Feels better now with some reassurance. Two new leaves are currently unfolding themselves. I'll see if the same thing happens with them. :)
