Looking good so far. Just some parts of the face and perspective that need some fine-tuning
- under the chin should be visible
- make the upper lid of the farther eye is more rounded due to perspective
- bottom lids of both eyes should curve up, and add some creases to push the expression
- push the cheek out and define the jawline, and I'd recommend u add the nostrils to better show the angle of face
- push the left shoulder farther back bc the body is in 3/4
- arm shape is a bit wonky, and make sure to define the elbow joint
- I'd also recommend u draw the collar as shown in image
Good work tho, the pose is dynamic and the expression is good 👍
