That is a nice yote. You stretched it in a shape that is not the best for selling. Not sure what you used but it looks like 2 sticks nailed together and just pulled out at the bottom making the hide shape triangular. Also if you are going to hang it in the house you have to get it tanned. If you don't the bugs will eat the skin and it will stink even if fleshed right.
Not sure if you can see the pics that great but this might show you the shape a bit better. I usually stretch mine too wide I learned this year and I just started to slim them down on the board now. From what I have been told long and narrow is the way to go.
