I'm going to be honest.

its a good start! I don't understand your use of the black on the blue. The "eyes" didn't appear as that to me at first. You need to work on your airbrush control, as i see some "spiders". You also need to practice your drop shadows on the peel back as well as the "depth" in the blue that it appears you are trying to achieve.

I hope my comments come across as being constructive, cause thats what they're meant to be. You show potential, just need to practice...

At this point I give you a 5 out of 10.....

Remember...practice, practice, practice, practice....
