Your models look nice from what I can tell.
Two observations that might be of use:
• "Go to hell" is perhaps not the greatest name you could pick as a vendor of 3d models. Perhaps go with something more neutral, or edgy in a less radical way?
Not saying that is directly responsible for your sales, but it´s not exactly a welcoming sentiment. "Go to hell - buy my models"... ;)
Duplicates:
You have several models that are mere duplicates of each other, and the only difference is the color (as far as I can tell).
As a professional buyer, this would put me off, as I can easily change colors myself - and I am not going to puchase e.g. 6 identical models with different colors to get the option to change colors. It seems like a cash grab, or it looks like it is made for hobbyists. Suggestion: I´d simply offer 1 model and then include the different colors or textures in the same file.
I hope this feedback is useful :)
