Hello! My name is Zechariah, and I aim to give fair and helpful critiques. This process involves me explaining what I personally see as flaws/mistakes (AND WHY THEY ARE WRONG) and then suggesting ways to improve/fix them. As the artist, you are entitled to your own styles and opinions and may disagree with w.e I say. But I hope you still find my critique fair :}
The ear is wayyy too small in length (top to bottom) and width(side to side). The ear should be about the length of the eyebrow to the noseline. Also, the ear needs to be moderately wider. The eyes are a tad too big for the face and too spaced out. An average space between the eyes is equivalent to one eye. The eye is supposed to be placed approximately halfway of the head/face. The lips are also very large, and could use some shrinkage. Overall head structure/skull structure seems to be too top heavy. I suggest a shrinkage of size on that part.
ARMS=Since the body is so large, it is difficult to determine if the arms are too short or too long but the hands are definitely too small. The left hand can cover one eye. When in reality, hands should have half or more of the face unless this is an infant/child. The right side's hand looks better. The left arm when it connects the bicep to the forearm, it looks very unusually thin and boney.
this figure is too huge in proportion to any of her features. To "fix" this drawing, you have to first figure out what is the definitive size of your character. The pelvis bone seems really low, I suggest you raise it higher. Her breasts look too lopsided or uneven. Both breasts must follow the laws of gravity. Finally, the arms do not have the same muscle tone as her abs. Her abdominal muscles are huge and defined (albeit missing obliques and such) whilst her arms are really thin. When drawing, make sure to take into consideration muscle and fat and that people carry more of it in some places and less in others, but if there's a lot of fat on one place, there's gurantee to be some fat in other places. Even if this includes broadening her shoulders
I suggest you study the form and structures of the human body and it's extremities. This includes anatomy/proportion research. Overall you did an excellent job, and I look forward to more of your art.
