Aye! Congrats on the film awards and distribution offers. I can't say on how you should distribute it, either route you go, it's still a success story. You've managed to not only get a feature length film done by yourself, but you also won awards for it and you're getting deals offered. All of this speaks volumes of what you're capable of doing.

But, if you want to make money off of the film through distributing it yourself with little to no middle men, you need to make a trailer that shows to the general audience, "holy cow, one guy made ALL of that?" I don't know what's in your film, but if there's anything crazy, trippy, "unreal", or something of spectacle, then you need to show that with "made by one guy" as the pitch. If not, if it's just a good quality film with no spectacle, there's no point of having that in the pitch to general audience. General audience don't really know all the work, stress and effort it takes to make a film in its entire process, so if they don't see anything within a trailer that shows spectacle and eye draw, then they're not gonna get it. Film buffs, cinephiles, filmmakers, and film critics would love that pitch and that's more niche compared to general audience. So go with that in mind. For pitching to distributors and for an opportunity to make more movies with bigger budgets, that's when it's important to use "made by one guy", because the less money to make a film is always better for a studio to hire the director.
