IME, perfectionists rarely get as much accomplished as hacks. On the other hand, hacks tend to fizzle out faster, so you'll need to compromise.
In bands that I run, I follow the Microsoft model: Create an idea for a product, market the product, create the product, and then fix bugs. And even companies that don't follow that model will still need to fix bugs later whether it's a car, children's toy, or software.
It's more often that a band's 4th album will be their best material instead of their 1st. The first can be great because it's fresh and raw, but the 4th album winds up better because the band has more time to develop their chemistry, songs and show based on the relationships in the band and feedback from the audience and other stakeholders. In terms of the OP's situation, I would just state that it's just the beginning and that the best is still yet to come. The first recording is a stepping stone towards your future, not the future in and of itself.
