Test tube?
It's kind of weird how a vampire would fit in with science, but the idea is still nice. I believe that this could have had some more detail but it's decent because the colors are good. These are the kinds of colors you should use more. Of course, you do always go for a dark style which doesn't use bright colors. It looks more like a Frankenstein's monster like creature than a vampire. I guess the stitches make me think that.
The use of markers isn't half bad in this, although it isn't of the highest quality. It was great to include a description as well. It's things like this that make me sad that you only managed to submit a single thing. I like how the light appears in the middle of the creature and slowly radiates the space around it. You're still keeping the pointed fingers.
