Tpoe's stuff

It looks pretty uniformly dithered to me - maybe break the pattern up a little?

I do think that less is more in the case of something as cartoony as your dragon's design. Maybe a few patches of texture on the knees, elbows, back and belly - or maybe just make scale marks like on This dragon?

Well in any case I'll get back to that dragon later, at the moment I'm mainly working on that Ringo Star picture and this one.

the alligator: you texture in bands, and there is no specularity which could destroy this impression. you still shade rather flatly and you seem to be squeezing the shades in a confined space. the shoulder looks like a ball, i think you should fix that.
the issue of the first two pieces is the shading, which is lazy (reduced to a minimum/ a level of seeming incompletion and not terribly accurate).
the second portrait's pretty good, but i'd like to see the reference, a wider range of value, and you re-doing the hair.
also: you need more practice on antialiasing (thinking of the ringo portrait).
overall you're not that bad at all!
