Ok, i'll participate. First builds are always rough. Everyone gets better with time. I am actually very embarrassed about my first one. I went at it again after learning from that one, and did way better. Glad I did. I've since been focusing more on props rather than whole cosplays.
Well I would certainly like to say that I have improved a lot.
Here is my first ever Halo helmet, made it when I was 10 (I think?)
Then my first foam helmet and chestplate (these were freehanded)
And my current build, helmet to be replaced
