Very impressive - much better than mere 'placeholder' and the ability to construct from parts increases their value many times over. With higher res lightmapping they wouldn't look out of place in a game at all.
If you've purchased some textures then maybe you should make a small charge - at least to recover your outlay - they are worth it.
