Ok, great. It's good that you have an idea of how the knife will be used. By "your vision" I meant that if the knife you used for reference had a smooth handle for instance and you felt that finger grooves would look or work better then you can do that. Or if the original had a wood handle but you felt that Micarta or G10 would be more durable for the environment in which it will do its work, by all means make that change. You can change any aspect of the design or construction you like. If it is structurally sound, aesthetically pleasing and well designed for its intended use then you can make any changes you want. Or you can design it from scratch with any features you like. When designing a knife from the ground up always start by asking the question, "what will this knife be used for?" Rather than just trying to make a "cool design" and then asking yourself "what can I use this thing for?". Always start with the tool's purpose for being because that will dictate most of the specifications of the knife. The blade material, thickness, shape, type of grind, finish, handle size, shape and material and more all relate to the purpose of the knife. Yes, those are good videos but please investigate all the information in the Count's post.
