She seems a little crammed in there, especially on the left and right. Perhaps expand the canvas? 

I'm wondering whether that rim lighting is neccessary, and there are a couple of single pixels I would do away with.  

Really like this. You've got the rythmn down to a T.

I think the roof and walls are a little over-detailed, but the banners and tree are curiously evocative.

Reminds me of the protagonist from 'Canabalt'. I don't think the arms need to be raised as much as they do. 

I think this would be much better if the top of the tree and bottom of the island didn't touch the edge of the canvas.

Incredibly taut neck muscles, but I suppose she's bound to be a little tense with that Chesire Cat phantom groping her breasts! The belly-button is a little long too, but the pixelling and details are nice, especially that half-on shoe.

Incredible lighting, and the rendering of the teeth is perfect. 

Really beautiful. The eyebrow and eye are particularly expressive.

Thanks for the happy birthdays Jalonso and Mandrill. :)

Thanks Mandrill. I think it came out okay!

Certainly wasn't expecting this from the preview! Love the atmosphere and that background blue!

I think we should focus on the amazing serenity of your portrait! An absolutely lovely piece.

The line that separates the lighter half of his face from the half in shade is too straight / sharply defined. The likeness is there though!

Fantastic use of the purple, and the texture is similarly well done. 

Ahh. Byron. Let's see if anyone gets that reference!

Ahh, I was waiting for somebody to do this. Brilliant pixelling.

Haha, these are great. Each one is wonderfully expressive.

I can't entirely discern what this is. I gather the moving element is some sort of tail, but everything else, including that transparent section, just confuses me.

A fascinating style. 

I like these. The uniformity of style is appealing.

The text makes it seem as though the men lowering him down drop the rope. If this is the case, then I think having a longer rope would work better. At the moment, it feels more like a snap.

On a rather odd tangent, I was reminded of this passage from the H.P. Lovecraft story 'Under the Pyramids', which you might enjoy:

"I have said that the falling rope was piling up about and upon me. Now I saw that it was continuing to pile, as no rope of normal length could possibly do. It gained in momentum and became an avalanche of hemp, accumulating mountainously on the floor, and half burying me beneath its swiftly multiplying coils."

Thank you Daruda. I appreciate that comment! 

Really love the little details here; the hair movement and torso rotation are great.

How can anyone compete with such beauty?
