Aesthetics and Kant

So, i have been reading lately a bit of Kant(critique of practical reason and groundwork of the metaphysics of morals,just so you know approximately where i am standing).One big problem that may seem to arise from his theory is that it is too strict.It relys so much in practical reason that it enforces humans to forget,succesfully,their aesthetics and act rationaly through the categorical imperative.Kant's opinion is that you have the right to do it,as you can imagine yourself being in a world which aesthetics can't affect you.So,my main point is that he overcomes this problem but his theory, inevitable, carrys a characteristic which enables a clarity in acting ethically ,but, at the same time has to be applied to aesthetic beings.It's like this theory makes sense in a world where reason dictates ,but there are so many factors to think of when you suddenly fall into reality.Because we find ourselves being in situations where it is so hard to act according to this mentality,does this actually prove we should forget about it?
