i believe in bubbles!! :D :D :D hehe

uh, seriously... in my most humble opinion-

heavily changed- if still resembles a photo, YES
photo manips- " " " then YES
images containing 2D elements- & it is all the artist's own photography, unless they got permission to use a part of someone else's (like their eyes rolls eyes) or an antique photo of great grandma & i guess a little fake lightning, bubbles & such is alright but discourage heavy use of tubes
stock photos- NO
3D elements- like Bryce & Fractals, etc. NO

the photo gallery is so HUGE as it is, the 2nd largest at RR
Mixed Media hardly fills 2 pages a day
