Lines don't "get" crooked. It's not a bad tattoo, but the design could be better. The script is too close to whatever plant that is. The 1 in Psalm 91, the 5 in Her 13:5, the "I' in the quote is too close and looks like a 1 and the spacing is all over the place. Having said all that, most people wouldn't even notice. The only reason I bring it up is so you do your homework next time you get a tattoo. Script is NOT easy to do, you need to find someone that does a lot of it and is really, really good.
