This is looking really good! Some shading inconsistenciea like the left eye too dark and some shadows too bright or missing but overall excellent imo
If you are struggling with proportions then I recommend not to shade at all, so you can focus on block ins more rapidly. I know itβs hard to avoid the urge to shade or render after you try it tho π but totally worth just focusing purely on measuring and blocking in a few figures instead of doing two skills at once (block ins AND shading practice)
