Hello, it's a pleasure to meet you! I like the idea you have of using the fish in your trailer animation. My idea would start by panning into a table in a room holding the aquarium and you would see a variety of fish swimming. It would then move into a scene with the two fish in the scene of your choosing to breed, probably the most vibrant ones you have to catch the eye to keep the potential buyer or investor hooked. Then we could show how those two fish evolve into the next type of fish. Following that, a new fish could swim into the scene and those two could also breed to evolve into the next fish. I would just need details or a chart explaining which fish start breeding, and what they evolve into. In the animation editing, we could also include the variety of fish to choose from, the aquarium tank options, or more. We would just need to work together on what exactly you are looking for and the styling once I would be able to see the fish and aquariums.
A little about me, I am currently in game design school and have completed modeling and animation blocks. I currently use Autodesk Maya for modeling and animation work. I would love the opportunity to work with you on your project. One of my greatest strengths is I value communication and keeping constant contact throughout the whole process so we both are pleased with the results! Thank you for your time!
