Another art thread! So happy~
Anyway, I wouldn't be able to give detailed critique or whatever you'd like to call my nagging because I'm currently on my iPad, and going back and forth is pretty tiring. Your first one is really good; it's my favorite out of the 4. The second one had an awkward hand. The biggest thing I noticed in the third one was the clothing folds, which should be a bit less bulgy. The fourth one was pretty cute
What did you use to draw these? O.o
Oh, and about the pictures: Add the tag around the picture links (taking out the spaces) for it to show up immediately. It's preferable to link with the "Direct link", but I'm not sure if dA has that...
