hey there think you have a very interesting style and feeling to your work. The portrait 4 images in is really good. Like how you have limited your pallet. You have good understanding of value relationships. The eye details and light reflections are pretty amazing good job there. I guess just keep studying as I am sure you have and just keep adding that knowledge to your work and explore you style further. Really like the dark surrealist feel in your work it work well. I think a bit more anatomy knowledge would just help give your figures a bit more solidity.
