MaxPOWPOWPOWPOW-ERRRRR!
Holy cow it has been a long time! It's good to see your name on the forums again.
Welcome.
I do like the overall feel. The text has something about the change in color that bugs me, but I dunno what I'd change.
It also looks like the box is on one plane, and the birthday cap is on another. Like the box is leaning backwards, and the hat is leaning forwards.
Lastly, it looks like the reflection of the box is a little too strong. Maybe a little bit less opacity.
But other than that it's mighty fine. Still could use more cow bell as party favors. :p
