Overall help/critique before i start colour

[lime jungle]

Doing art trade wanna make sure its good!

[drifting lintel]

woops, kinda late, but I'd personally raise both shoulders & thicken the neck a lil bit

also (unless a stylistic choice) reduce the face size (mostly the cheeks) & lower a bit the nose/mouth (could be a tad bigger too)

some top-left hair volume would be nice 2

nitpicking mostly, looks gr8 so far
