I like the 3D part. It has mayby too sharp and jagged edges in some parts, but it's fine.
The 2D is absolutelly perfect - I like especially those "rays" - how did you made them? Witho some special brushes? And very good idea was to use red collor for those small details and lines
Awesome all around. I love the movement, and the flow. The color choice is really nice also. The mood is awesome, very bright and pure. Your 3D Render compliments the them well,and it works well within the piece
