You did a pretty decent job at coloring but England's form is a bit 'stiff': his shoulder (the one closest to the foreground) is held too closely to his side for someone in that sort of 'I just got up' postion and make him look very stiff. Also, the tip of the ear should be level to the pupil in the eye and should be place farther back on the head. when drawing the human form its always easiest to start with a model or even just by standing/sitting in front of a mirror so you can get a good idea of how the antamony should look like. What I like is the folds you put into the blanket and shirt: folds are rather tricky so to see them done well is a treat.

Probably the best advice i could offer you is this: before you draw anime you should try drawing real life portraits, they're not as fun (trust me, i know!) but they help you get a good idea of what the antamony of a person is so when you draw in other styles (such as anime) things look 'right,' so to speak.

I hope that was helpful ^_^
