someacnt_Can I ask for how to remedy my build here?
In general, there's a tutorial on the Minecraft wiki just for adding beauty to constructions, and the Construction category on the tutorial page has other tutorials for buildings too.
There is a guide I used to swear by on minecraftforum.net, might be this one but I think it was longer
Tutorials/Adding beauty to constructions
This tutorial is to give aesthetic advice for your home or building. The beauty in exterior design can come from many different elements all interacting together. No matter what architectural style or color scheme you choose, the most important aspect of exterior design is adding details. This means that if you're building a blue colonial style home, you want to make sure to use different shades of blue blended together, maybe with another color as an accent. Try not to make your build look like a box. People may not always agree with your style, but attention to detail is undeniable.
