Unsure about the quality of my piece

[sour eagle]

Hi, i have began to draw this and i have been wondering about how good the perspective and expression are. Any tip and critique to improve it would be welcome

[unique gazelle]

the arm should be a lil longer than the forearm, the face should be slightly angled upwards from the neck and the hips wider/ torso slimmer
here's my ig if you want more references for poses i have a few on there: the.sleek.edge
