Yeah, something about that size could be quite pleasing.
What you've basically got is a great base - now you can grow whatever you like to accent that base. Dan Robinson wrote a seminal article published decades ago entitled "Focal Point Bonsai Design." Your focal point - the main interest in your tree, to which you will want to draw people's eyes - is that base, with its nice trunk movement, bark and nebari. The branching and foliage are merely going to play a supportive role, framing and drawing the eye back to the base - the focal point. People have studied how the eye roves and roams over a great piece of art, and invariably it is a dance around some principle focal point to which the eye is drawn back after each excursion to more supportive, more peripheral aspects and areas. Hope that helps.
