Crystal Illustration

An illustration I made for a school project. but I ended up not using. 
costs 10 points to download, it can be opened in any Illustrator program, and you should be able to change the colors. 
My watermark is on a layer that you can hide. 

RULES: 
-You can remove the watermark but you need to give me credit in a description, with a link to my profile and to this original. 
-Only for non commercial use
-Can be used as an effect in an illustration/artwork, in designs etc. 
-I'd love to see what you can come up with using it for, so please link me with your artwork
