Hmm.... 'kay, I got some.
Drawing 1:
1. The proportions are pretty good for this one, so, that's plus number 1.
2. However, the hair looks a little funky on the left side- it doesn't stick out that much, it also goes down.
3. I think there's too many 'spikes' going down for Conan's hair, but since you didn't have a guide, I can't blame you.
4. You have some strange creases on the right (the right you look at) arm. The arm also 'ends' too early. It should be thicker at the top.
5. Somehow, the eyes don't make me think of Conan, but that's hard to do seeing you have to have the right thickness and whatever. I think his eye needs more light.
6. I think his head needs to be more round
This one was pretty good. I flipped it using my computer and there weren't any extreme errors. However, his left (our left) shoulder is a bit low.
Drawing 2: (I should eat breakfast soon....)
1. Shinichi is too short (or Conan is too tall) Conan doesn't even reach Ran's hips! ^^
2. In order to fix that problem, make Shinichi's legs longer, and Conan's shorter. Gosho Aoyama said that Conan is approx. 4 heads tall, and I think Shinichi should be seven.
3. Their right (our right again) arms are a little awkward. They should overlap the body a little bit.
4. The left arm needs some creases at the elbow. I hate drawing those creases...
5. Shinichi's hair is a bit awkward. It needs one more tuft just on the left side of the head, coming behind his head.
Reasonable, you just have to adjust the arms and legs a bit, that's all.
Drawing 3:
1. The first thing I noticed was that Conan looks like a six year old still. (and he's much too tall for that.) Either give him Shinichi's face or simply make him and Ai shorter.
2. Their heads are too flat! Draw circles for the head! It actually works! (just tried and had success at last...)
3. Their necks are a bit skinny. Make them wider at the base.
4. Um, is Ai's left (our left) arm end in a hand, or is that her sleeve? It's hard to tell. If it's her hand, then it needs more detail on the fingers, but if it's the sleeve like I think it is, it shouldn't really be creased like that. It should be flat.
5. Ai's hair isn't detailed enough. But you'll get better at that.
6. Ai's eyes (hey, homophones!) need more creases. You need them above the eye to show her eyes aren't open all the way, and then you need the eye brows.
That's just about it! (now to retrieve my chicken from the microwave...)
