Pleasure to meet you, Mr. Brown.
I liked your flash very much. It was a solid little psycho spooker that had that partiucular, eerie-creepie feel to it that is critical for similar animations. The rhmying was a good idea, and the lack of a very obvious metric rhythm made ot even more bizarre. The textures were awesome, and the fact that Gregory can assimilate with the ordinary folk with stains of blood on his cheeks made me chuckle. The fact that he's talking to us was a nice touch, making the end especially effective.
Nevertheless, our pop culture is a bit oversaturated with these kind of grotesque, psychotic type of characters, and while I love most of them, it is pretty difficult to do something with them that hasn't been already done. While your flash and the character of Gregory was indeed moving confiently among the traits of this genre, I suggest you to give him something that makes him stand out from the rest of the freaks.
All in all, the flash was solid, enjoyable and atmospheric, I hope this isn't the last time I've heard of Mr. Brown
