The castle is too saturated, and overwhelms the foreground figures. Toning it down to resemble the original source would help. The entry is a bit too filter heavy for my taste, but it's a good composition.

Wow, really went for the swirly whirly effect through the whole piece. Reminds me of a Velvet Painting... on Crack. hehehe. The construction of the "Seahorse" dragon is really quite nice.
If this isn't viewed in HIGH RES you can't really appreciated the work that has done. The painting textures are wonderful. Good luck author.

Thank you.
