Would really love some feedback on my drawings!

Way to go! This is a huge undertaking, and you're doing great so far! You have some really nice lay-ins and even some recognizable likenesses in the group! (I'm referencing all of the portrait posts in your album.) Here are a few things I noticed. For now, focus on linear lay-ins (27, 28 are great examples of what I mean) these examples are well structured, and simplified with clear plane changes visible without relying on added values. Aim for this level of clarity in the linear lay-in phase. Hold off on adding values and shading, even in the lips/eyes, until you can construct a solid frame for the face that you’re happy with. (You can’t paint the house before you lay the foundation!) Also while you’re drawing, mirror or flip your portraits to check your accuracy along the way. Take a pic with your phone and flip the image or just take it to a mirror and look at the portrait for a few minutes. Immediately you’ll see mistakes jump out at you. It’s a huge help when doing lay-ins. For reference check out these videos from Basics 1) How to draw accurate proportions 2) Project/Demo/Critique - Measure Proportions 3) Project/Demo/Critique - Portraits in Perspective 4) Study Andrew Loomis! Most of the issues I see are based on proportional layout which Loomis covers in depth! I attached a few pages from his book Drawing the Head and Hands! Here are some specifics Proportions and Alignment of Facial Features: Eyes are too large and/or too close together (15, 18, 20, 21), noses misaligned or not properly structured (18, 19, 20, 21), mouth drifting off-center line of face (16) no structure to mouth or lips/appears cartoonish (21) Structure and Form: 17, 18, 21, 22 lack underlying 3D structure of the face and skull (you were able to convey this well in 27, 28) Line and Curve Construction: Use more straight lines to help build accurate curves and contours, particularly in areas like hair, eyebrows, and facial outlines (15, 17). Construct curves using straights to better capture subtle angle changes in the face Values: Values are either not clearly separated or are applied too early in the process (18, 22). Focus on creating a clear distinction between light and dark areas using linear line first, and avoid adding value until the linear structure is well-established. Hope this helps! Can't wait to see the next batch!

Help greatly appreciated!

To start with, your drawing is lacking structure. The shadows are less convincing because the structure and anatomy isn't there, you just drew the contour which makes the drawing look mushy. I did a quick sketch to show you the stages you should go through that will help your drawing, I hope it helps :)
