Sparkle Spotlight: Paint blot realistic art

So I got another new set of Prismacolor pencils, this set has 24 pencils instead of 10 like my last set. So, I have been using them like everyday since I got them. This is one of the drawings I was most proud of because to me it looks pretty realistic. I'm still learning about these pencils and realistic coloring, so I'm gonna call this one a win since a lot of my other drawings haven't turned out so well. 

This was my finished drawing. I used the reference image bellow. It looks pretty similar except for the middle portions colors.
