They're pretty clean, and the paint job quality is decent, so you've got that working in your favor.
Keep in mind that painted models generally are harder to sell unless you're selling a whole army at once (and that prices it out of reach for many people) and an unusual paint scheme can be particularly hard to sell.
Which isn't to say that you can't find a price that somebody will pay, but that price will probably be below the retail price of the models.
If you're trying to make money on painting you're better off trying to find commissions, people are much more willing to pay for those.
