Welcome to the forum...!!!
The Coop you built looks fantastic...!!!...Great job!
When you can give more information, even a rough sketch, I think most here would love to help you improve your skill sets in woodworking.
However, if you can build a Chicken Coop like in your photo..."totally freehand"....(with only hand tools?) then you are well into becoming a great woodworker, as that level of carpentry skill is well beyond what many DIYers just starting out could pull of as their first project...That is a very respectable woodworking project for being your first one!!!
