yeah sure Atom I respect ur point of view but, look u can smudge a little place to get ur liquid view which u want then u can use the eraser to remove blured edges (I mean u can then draw and edit ur drop by the eraser which is the jocker imo in PS). then with burn and dodge u can add some depth.
MEthod 2 for making splatzz and blood fx:
get any ink or any liquiid and drop it on a white paper...it will make drops shapes and stuff, now after it gone dry scan it , then in PS use it and adjust ur colors also u can define it as a brush
enjoy
