Best way to get good honest feedback on your photos is to post them on a dedicated photography forum,many of which have their own critique sections.They dont usually hold back in their honesty but at least you learn and dont get someone telling you a shot is fantastic just because you're one of their clique and wouldnt dare say that there was a big patch of burnt out sky or poor contrast, etc.
Good site and photos,nicely set up,your second sunset has a squint horizon though.
