Princess Serena / Sailor Moon

Hello, it has been a while. I have been very busy with work and everything so I do not get to draw and post as much as I would like to. Some time ago I got a new Wacom Bamboo tablet and I love it. This picture is for my friends niece who is 8 and loves Sailor Moon, so I drew this for her birthday. I know that there are some mistakes and stuff but I would like some critiques please and thank you.
