Even if this is a master study, I would still definitely watch your proportions, also, link the study, so I can compare the two.
Also, your anatomy seems borked in places. Namely, the legs look kinda flat, the shoulders look above the body itself. The face isn't terrible, but I'd watch the shading as it looks like its made of watered clay lol.
Your coloring on the fire part of the breastplate looks nice though
Just remember to do prelim sketches to get your anatomy right before diving in
Glad to see you finishing school though! I just finished mine myself -.- it was overly tiring in the end.
Keep posting though! You can only improve more and more
