Won`t you come
No in all seriousness, this has some unique creativity here. I love the purples all throughout this and the shadows in your shading and coloring, the background is a good scene and creates a theme and makes you think. I do like that one character over-top the other, but the porportions seem a bit off there, maybe the angle needs to be altered a bit, but other than that I do like this. Your background is very detailed and has a lot going on, so that shows that you put some real effort into this.
~~THINGS TO IMPROVE ON~~
Just work on positioning and porportions.
