Holy shit, why has no one commented on this yet? This looks phenomenal! Makes me hungry just looking at it.
At a quick glance it looks 3 dimensional, but a closer look shows that it is very flat. I'm not sure how you could correct this, but perhaps make it pop a little bit more?
I also noticed that the edges of the cone are kind of blurry, almost seems like you're using the blurriness to hide the fact that it's 2d.
The chocolate dripping (I'll assume it's chocolate) doesn't really make sense there unless it was dribbled on, but the liquid itself looks very realistic, almost to the point where the drizzle looks like it was put on afterward, and it's not a drawing. The colour almost reminds me of black sludge, but it's so well drawn that I don't really mind. Really well done!
