The colors are the first thing that jumps out at me. They are absolutely stunning visually. They play beautifully off the heart in the right side of the focus. There is one purple crystal that almost pulls the focus to the left of the heart, but the heart maintains the focus because of the patterns on it.
I also like the way that the heart is not dead center, but it has all of those colors in the soft background to enhance the "out of place" feel of the heart itself. The title is perfect as well. I will admit that it helps that I love all of those colors, but I think I would have liked this in my least favorite colors as well. Stunning.
As said before, the first thing that POPS about this picture is it's stunning colours. They mix well together, and the reflection they have against the small heart is beautiful.
A second thing I also really like about this is the focus- the blurs above and below create an almost... magical feel that enchants you completely- especially the top where it's a mix of colours. The heart is beautiful focused where you cant help but stare at it in awe.
Overall, the artist really was able to capture our eye and wow us with a simple yet stunning piece. Great job.
