Marceline and Bubblegum

Hello.
So here I go, please bear with me as I am writing in the dark at 11 PM.

Firstly lets start with the style.
I really like the way you have done this. Instead of going the Adventure Tome Original style you choose this one. It is different and I find it intresting. I find it intresting because it shows adventure times Marceline and Princess Gumball in a more unique form. It still gives off the original idea but in a more different and almost mature way.

You have really created an effect with this image, havent you? Marceline seems more spooky and PB looks timid around her yet you still keep that cartoonish kinda style. I think the colours have made that effect. Also the body language and facial expressions really show what they are feeling. For example PB is clutching her dress and looking akwardly at Marceline which shows she isn't too comfortable at the moment. On the other hand Marceline is hovering around PB and is making a claw shape with her hands which would probally be rather intimadating, especially when blood is pouring out her mouth. That shows Marceline has had a snack on some living thing close by and is still probally hungry.
Oh, and the attention to details. Every part of the image is filled with shades and colours, just right to give it that great effect and atsmosphere.

To conclude you have added great effect and atsmosphere but still kept the original design of the two characters.
I can't find anything wrong with it so all I can say is:
You are awesome, your art is awesome, your style is awesome... I think you have exceeded the awesome meter of life.
