Jordan, that's an accident waiting to happen. It also looks like the ladder is on a snow covered or frosty patio. I can see that the stair railing is stopping you from getting the proper angle, but you could do several things to do that window safer.
- Use a taller ladder, and place it over top of your window set to get the proper angle.
- Have someone foot the ladder
- Use a smaller ladder, at the proper angle, from the stair landing
- Use a ladder stabilizer, and rest it on the sill to at least discourage slipping backwards, and also improve your angle.
- Use a pole
