I didn't say this before since I assumed your models were all "rough drafts" or the like, but don't you think you are rushing this a bit? look at the images of the model, and I don't really see a CST-100. Just a rough generic capsule. The edge where the heatshield meets the sides of the capsule comes to a hard edge. That isn't right, and definitely doesn't match the CST images. Also the accent cap doesn't match any pictures, either. It doesn't blend into the sides of the capsule.
It's been less than two weeks since you started, and addons take time. I'd rather wait longer for you to make a good looking CST-100 addon, then fly this how it looks right now. Trust me, I have a number of SC3 addons I've made for myself, that I wouldn't dream of releasing since I'm not happy with how they look. Take pride in your work.
