First off TJ let me say that your carving and lettering is very nice. If what you did on the seat isn't the Logo of Red Horse Choppers, it should be. Secondly and from a fellow riders point of view, the top lacing would start to dig in to your leg after a while. Thats why most are stiched at that seam. If you don't have your own leather machine, and you should if you are going to do this type of work for profit, the local shoe repair guy does and you can work something out with him. Have them use black and you'll have a kind of pin stripe that will look great on that top seam and the short, vertical one. I like the lacing on the bottom very much and think it is unique.
You asked TJ and those are my thoughts
