I really did enjoy building this model, however LEGO need to work a bit harder on 'Attention To Detail'. If you look closer at the 'top' of the neck vertebrae from the side, and follow the top of the spine from the top of the head to the body, u will notice a 'dip' in the middle. U need to add another single 1 x 2 block (tan) underneath the top 'pointy' brick, to make it uniform. Also, the entire second tail segment from the main body is 'lower' on top than the first and the third tail segment, which makes it look smaller, out of place and like it should have been the third tail segment instead? To rectify this, I added a further 6 x 1 x 2 (tan) blocks underneath the top 'pointy' blocks to compensate for this. The second tail segment is now the 'same height' as the third tail segment and it no longer looks out of place. Overall though, a really different and enjoyable build with great use of colours. Lastly, the impressive size of this model and the new parts provided for the movable neck are terrific!
