Overall critique

[rocky igloo]

not mine but what currently feels off in this drawing in your opinion?

[muted river]

Idk but the face kinda looks off, it may be due to lack of detail compared to rest

[edgy estuary]

i think just adding some eyelid shadow could pretty much fix it

[calm canopy]

not too much need to be fix, just need more polish, overall is really a great work
