Better than I could have done.But it needs improvement. First you might want to rotate it in a program. Second, I can't tell from the official pic, but what is the stuff at the head.
Then, the turrets or whatever they are on the top of the "skirt." The arms have a ball shape to most of them, yet these don't are just all over. In other words, it looks like you rushed it. Ovals, circles. diamonds,etc. Try to make them all circles. Yes there are a lot of them, put you are trying to do the best work you can. Rushing it won't help. Lastly, there are the lines. Again, it looks like you rushed. Try to make them straight by using a ruler or a straight edge. Just don't rush and that's all I have to say.
