Very cool stuff. I think I’ve seen some of your posts on cgFeedback. 
A few crits… (edit : A lot of crits
)
• Reel is about 2:00 to 1:30 minutes too long. 2 Minutes is probably the longest you want to go.
• Get closer to the model. The camera does zoom in but I think we need to actually see how you handled the character faces. (This isn’t a Dreamworks reel) But Dreamworks likes to see a posed spinning model and then a close up spin of the face, that way they can tell if it has appeal or realism, ect.
• First guys butt crack is extremely distracting. Don’t know whats going on there.
• Anatomy looks good, though some forms feel forced. (If that makes sense) Side calf muscles, knee, obleaks, butt to leg crease…
• Push your poses and really try to emphasize story. Your punk guy suffers greatly from this. Great modeling though.
• Punks clavicle might be a bit too low and the tears in his pants feel all even. Your also getting spec of reflection artifacts around his hair when he turns?
• Watch consistency, make him brown clay with wire like the rest.
• Does Post Apocalyptic lady have a face? It’s hard to really connect with the character when you don’t see the face. This is something I even saw on cgfeedback when you posted. The work shows but it feels like a throw away character… like a character that you would see in Borderlands that you would just mow down to get to the next enemy.
• Steam punk female - start on her face… then move down.
• She is missing weight too. She is casually standing on one leg with a giant heavy rocket on her back. Otherwise pretty solid modeling
• Old man head should have a turn around. And I might scrap the color version. The model is better then the shaded version.
• His ears need work. Wether or not the reference looked like that, the model needs to look believable and authentic.
• I’m personally not a big fan of the animal mech person. Sorry 
• Arm study needs work. I would probably take it out. The inner palm needs more reference. Proportions need adjusting; his hand is small his forearm is too long. This is something I would post to my blog or facebook but not in a reel.
• Monster head could use more variation in detail. If you squint everything feels even. (Width between wrinkles, depth and direction)
• Depending on the studio 2D work can ether help you or do nothing for you. What would benefit you more is showing figure drawings. Not only can you should that you can understand form and anatomy but anyone can look at figure drawings and tell if you can draw or not.
• Black and white digital painting has some big problems. It’s very air brushy. Air brush technique can destroy form. A better way is laying down 100% opacity color and make it feel like your chiseling out the form. I would look at Dice Tsutsumi’s work http://www.simplestroke.com/wp/Perspective in the windows is killing the piece.
• I would take out the Lara Croft painting. Sorry bud 
POSITIVENESS!
• I liked that you started with your best work first.
• You have some solid modeling stuff, now it’s just pushing it more and making then even more solid.
• Turns are not convoluted they are clear and at a good resolution.
• Although you are showing lighting and shading I feel like your emphasis is modeling. (without knowing the title)
Hope that helps. Quite a bit. Hopefully I didn’t talk your ear off.:o
