This is my first custom but I think I did well. I am slightly annoyed by how big his eyes are but I'm not sure i could've done much better. I used a few sharpies on the armor of the 10th anniversary blind bag brute. I have no idea what castors armor set is but I think the captain molds work fairly well for him. I was inspired by some of the halo books and knowing we'd probably never get an official castor. Please feel free to rate my custom in comments
