That dragon is great!!! The river looks a little blocky though with the tiles. You could achieve a more sleek look using sideways bricks and plates with the brown plates overhanging if you know what I'm saying
Nice work, the legs and tail particularly look good. I also like the head, although it looks kind of insectoid. With the title and layout of the MOC, I half expected you to have some Pokemon theme playing. ;)
Best use of bananas (aside from using them as fruit) that I have ever seen. The spider webs in the cave really add a level of detail that remains highly visible even though it is in the shadows. All of the colors in this dio really come together well. Attack!
