@swikni Good stuff!
Your ear looks perfectly fine to me, form-wise. I think probably the only thing I would do is rotate it a little – top half toward the left, bottom to the right, to make it more vertically-straight – and then maybe move it and the jawline leading up to it a little closer to the front of the head, but of course heads are different so that isn’t necessarily so. But you achieved a realistic form there, don’t worry.
