The colorization one is good, I'd take out the "Boo" and "Scared" parts though - they kind of "take away" the picture. Make the "Look me In the Eye" more transparent, as well - it'll add more focus to the colorization. The second one.. it isn't really doing it for me..
u need to really work on ur text. On ur 2nd one it doesnt have any glow and not much depth. Dont use the outer glow on renders :/ and try blending the render in more.
Top 1 i like the idea, IMO take out the boo and scary, and make the "look me in the eye" more visible with a stroke or diff color. 6/10 fix it and it look rad
the Halo 1 has to much outer glow and not enough happening in the picture. 4/10
