Take off all the tape and see how it went. If you got small amounts of unwanted paint on the screen, etc. you can hopefully scrape it off very carefully using the x-acto knife (magnifier advised for this). Also test to see if you didn't destroy the camera and if all functions seem to be working. If everything seems alright, you can breath a sigh of relief and move onto adding details if you would like. If you have already scared yourself to death with painting your camera, you can stop here.
