wow that took forever to load xD you should try using photobucket its a fun effect, bullet holes are pretty simple imo, i've seen some tuts for very realistic ones out there, if this is the kind of thing you like you should check em out not the kinda thing we normally see around here but its a good change imo
that is a lil different then wat ive ever seen b4. its not to bad maybe even ending a render in there might look nice? guess it'd depend if u found a good one. and like Daecu siad there are sum nice tuts on how to make other styles of bullet holes
