I like the portrait. I think there is an opportunity to deepen the shadows on the face. The value difference in the garment is greater than in the face, you may have been reluctant to lose details in the shadows but having some lost edges can enhance the composition. Also the lights are a bit washed out, you may want to look at increasing saturation when raising the value, this can be done by adding in high chroma colors into your light mixes. Save the low chroma high value notes for the specular highlights.

Great painting! But I want to get some understanding of where I can give feedback. What do you love about this piece? Where do you want to improve? Where did you struggle most? Let me know! Thanks!

Oh hey it's you Hey this is pretty good!Very excellent shape design on the face,I particulary quite like the simplicity of the shapes in the ear.Nice warm and cool contrast too,it remind me a bit of a Nathan Fawkes painting I don't have much critique,except for maybe in the forehead area where the light meet the shadows,there should be a little more warm before transitioning with the very cool shadow.JUSt to be consistent with temperature of the cheek and chin.(also here's an overpainting if that helps) But other than that,great work!Please keep going,we want to see where you go from here :D
