Some pictures someone sent me, is there any svorah that the first doorway would need a mezuzah? (its missing the right doorpost... but is kind of close... and has no lintel but it the ceiling goes down which kind of give the impression that it does..) The second picture seem to me to be straight out potur, but a general Shaloh, can a doorway to a room with no lintel but has a lower ceiling be in any way considered as a lintel? (think about walking down the stairs the ceiling is lower) Thanks

1)  I widened the gag of a chof pshutah (from the word lecha beow) to make it wider because there was more than 3 yudin between the words. Then , in order to make the chof pshutah more perfect, I attempted to thicken the regel with my rapidograph, only I started a bit too wide and ended up making a gap. see pic below. I am 99% certain that this would not be a shinuy tzurah in any way, however I wouldn't mind a second opinion before I fill it in and complete the tikun, which should look fine once it's complete 2) The vav from the word vechol above... 3) Finally, I have a house that has a very unique entrance way, when you walk down the walkway there are 3 metallic "archways" which are not there for support, but more for design. since it is in essence a mashkof and you walk through it, would they require a mezuzah? Its on the main walkway leading to the front door.
