Some Shailos...
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.
