This is a bit late post because I did not realized that wifi connection went off while uploading it. The first upload was failed. 
This is how my tower went on. I made many mistakes.
First, I made too tight seam allowance.
Second, I made the wings of the tower into 5. I must have been 4.
Third, the tower was too extreme to be sewn. Therefore, the final tower was a failure.
However I learned with terrible mistakes. It was my first try of making 3D object from a precise pattern. I am not good at sewing right now but I will try hard because I started liking it for the first time. I cannot wait to make real clothes that I can wear. 
( I stole the picture of myself from my friend’s social media. Well, I do not care since it was secretly taken lol no permission)
good job. % sides are Ok. it is allowed. please add a picture of inside and close up of seam when you can.
