The portraits are great. You're quite good at getting that balance, where it's not generic at all and not symmetrical, even when front-view. Something that drives me crazy is the generic face... I even found a website recently for a continuing education summer academy of arts where they tackle "drawing the face" and their example wasn't even up to snuff.
The "cow95" and "cow96" are great images. I like the fis-like creature in green. There's a delicate suggestion of detail without getting too sharp or lifeless, and I love the inventiveness. I'm not one for sci-fi or fantasy art, but this work is pretty good.
I do have to say, however, that the first piece has too many re-used brushes and brush strokes, hurting an otherwise well-painted piece. The 2nd and third images are fairly cliche in subject and pose, as well as weak in composition. The biggest thing you can be thinking about is composition and originality of pose/figure.
Congrats on the feature. That's a nice achievement.
