Hi hi~! I totally wasn't expecting it to be set up today, haha. You work quick!
Alrighty I don't feel there's much I can say about your newer piece - your lines certainly seem to be nice and smooth and have a nice flow to them. It's cute and works and nothing seems broken about it, so good job!
Now I'm not sure if you've changed how you do things from some of your older works so I picked Scarlet to write up a short critique on as she was a more regular sized full body character (your chibi characters are super cute though!!!)

Okay so the points weren't made in any specific order but here we go.
1) Think about the body beneath the clothes!
Take a look at the draw over I've done and where the body is beneath the clothes - things don't quite add up the way they should. The most noticable thing for me was that the thigh on our left vanished up at an angle into the skirt - but above that skirt there wasn't anything to suggest it would lead back to the hips at all.
A lot of people start of with the habit of drawing everything from the start - I totally get that because you have the idea and you just wanna get it out there on paper. Nothing wrong with that - so long as you take the time to re-visit and think the picture through properly.
It's always a good habit to think about what's beneath the clothes because the clothes conform to the body rather than the other way around
smile I always recommend to get into the habit of drawing the body out first as a rough sketch to knuckle out things like proportion and pose THEN taking the time to add the details once you've got that sorted.
2) Proportions
You mentioned you wanted to get better at anatomy so here are some very rough guidelines on some key proportions on the body to help get things lining up a bit better!
It's kind of cool how you can use different parts of the body as a ruler against other parts and how things line up with one another. A lot of people for instance like drawing the head because it can determine the width of your shoulders and how long the torso should be. Once you have torso, that then leads to the arms and you'll have your defined waist to ensure the elbows line up with them etc. It all sorta starts to chain along as you go
smile Fun tip: Your feet are roughly the same length as your wrist to elbow
biggrin In this case I didn't write it on the example I've drawn because this wasn't a real proper size character and the small feet are actually kinda cute X3
Another thing when drawing is to keep your limbs the same length/thickness. The arm to our left seemed a tad longer than the arm to our right. The thigh to our right was also a lot thicker than the one to our left.
3) Pose
A tricky thing that a lot of people struggle with.
Tip 1: Centre of gravity - This is where you focus the weight of how the character is standing. When you lean on one foot, it actually tends to be in line with the centre of the body - try it out, your body sort of balances itself by cocking a hip to get that the weight centered on that foot - allowing your other leg to be more free in what it can do. Unless of course you are standing with your legs spread in a straight pose.
Tip 2: For dynamic poses where you say have one shoulder slightly higher and I mentioned that hip cocking above? If one shoulder is up then that hip will actually be lower - so one side of the body is elongated and then the other is actually 'squished'. That hip that is higher is also usually the leg that ends up holding the weight too.
So yes - you seemed to already have one shoulder up higher so I went with that when I was doing my 3rd example about the high shoulder/low hip thing.
Also - it's very very odd to stand with both feet pointing outwards to the sides. Your feet naturally point forward or one will be straight and the other turned out slightly depending on what that leg is doing. It's always a good idea to stand up and try out the pose you're drawing so you can feel what your body is doing and where your weight is naturally going
wink Okay, that turned out a lot longer than I thought it would - sorry for the information overload!
Definitely check out the resources section in the guild though for more help with things like anatomy and proportions and all that and if you can't find something you're looking for let me know and I'll see what I can find for you
