First of all... HI!! Welcome to the guild! :O
On to the art:
I like what you've done here - you've got a nice grip on flat colouring with traditional media, and an interesting composition. The anatomy isn't actually too far off for anime, which is pretty good - that's just a bit of practice, so no worries there.
What I suggest to improve is to start bringing in the simple cell type shading (similar to your second post link) which uses one slightly darker shade. Make sure you pick a direction for you light source first, so you can tell where the shadows should be, and where the highlites are (IE: the darkest spots should be any place further back from the light or where the light would not touch, and the brightest spots would be the closest to the light, or where the light touches first). That should help bring some dimention in to your art!
What I found useful when I first learned to draw anime style is to start drawing just certain parts of the anime anatomy - like drawing a whole bunch of different types of eyes on one page. Like a stydy of those parts. By the time you've done about enough of them, you can pretty much do them without thinking about it - which helps to give you space to focus ont he more challenging things, like the pose.
Pose references are super awesome for studying purposes - you can google just about any type of pose (action, romantic, thoughtful etc.,) and come up with a ton of images - just make sure you credit if you use one! I like to use them when I'm trying out a new pose so I can remind myself how things bend, or where things should line up - it's especially useful for doing couple pieces, because drawing two people is always more complex than one.
Studying fabric is actually a lot easier than most people think - my suggestion here is to take an extra chair in your house, take a white bedsheet and a tall lamp with no shade over it (or sit in a place with bright lighting) and arrange the bedsheet so it has tons of wrinkles and shadows, then just study it. Track the way the fabric folds over on itself, and the types of lines it makes, and where the shading lies - then move to different types of clothing in anime. You'll note that anime folds are basically just like real life, only they're very very simple. Simplified things are often harder to draw, if you haven't already learned to draw them the other way - why? I have no idea. Something about seeing or something. I wasn't really listening in that art class, there was a hot guy across the room and I was distracted.
Aaaand I think that's it.
smile I really like your art, and I hope to see more from you as you improve - you've already got a good eye, so keep at it and I'm sure you'll be making some of those awesome traditional anime art with copic markers or something soon~
