Yes definitely. The faith counts. However this doesn't mean we should do imperfectly, but even if done imperfectly with faith it really counts. Lord Krishna addresses this question in the Gita. In Gita 18.48, we find,
Translation: Every endeavor is covered by some fault, just as fire is covered by smoke. Therefore one should not give up the work born of his nature, O son of Kuntī, even if such work is full of fault.
In his commentary, Srila Prabhupada says, In conditioned life, all work is contaminated by the material modes of nature.
The following verses say that by performing one's duty as per Varna, one moves along the path to eventually becoming a Brahma-Bhutah, which is a liberated state of existence.
