Fantastic work! I always love seeing all your projects! Feathers are a pain in the butt to sculpt I imagine, so no hard feelings about that haha. (unless perhaps you glue or attach them onto the sculpture afterwards??
well, in jurassic park, which this style is based, they actually used the Deinonychus, which is one of the larger raptors. The reason being is because velociraptors are believed to be the size of a large dog, while the deinonychus was roughly 5-6 feet tall.
