You get a 7 for sculpting green-stuff. A 3 for presentation, since it's pretty impossible to figure out what the entire thing is supposed to look like.
Umm... This picture isn't the best if you want a good rating... It's hard to see what it is... and what is it you want to show? The green stuff looks green-stuffish and the grey plastiv parts looks like a shot of my bits box... I would really like to see the entire defiler though! If you have detail shots like this, please make one picture with the model in whole and detail shots as well! All in the same picture! I think you have a great model going here though, so I'll give you a 7.
