One key difference that made your version of the sword still look significantly smaller than the original is the fact that positioning of the clouds matters too. Because clouds are also kind of a height reference, the further something reaches past the imaginary cloud layer, the bigger it naturally seems. In this case, you had the cloud layer roughly at the sword's handle whereas the original has them floating around partway down the blade.
As soon as I saw the intro I knew this was inspired by War Within. I think the original World of Warcraft cinematic was one of my main inspirations as a child that got me into 3D. Great video with good explanation
I am doing CGFast Track right now and I really enjoy it, each day I learn more within Blender. I intend to follow your work now and most likely sign up for one of your structured courses. If you put in the work you will learn and create. Thank you for teaching, rather telling people what to click and to do in blender. I can see you put in a lot of hard work.
One more quick tip, in comp try reducing the contrast of the object in the distance, this tends to give the feeling that the object is far away. This illusion tricks us into thinking that there is more dust/ atmosphere between us (the camera) and the object.
