Hey me too! I've only just started the 3D aspect of my university degree. Your stuff looks fantastic. I'm working in Maya currently and I haven't really begun texturing or anything like that, but here's a concept poster I made. It's for a fake animated film based on the life of Salvador Dali. Do you know what the difference is between working in Unity 3D and Maya? I'm fairly new to the 3D element of animation and modelling.
I think it's hard to compare Unity with Maya. Unity is a game engine and Maya is a modeling tool. Of course you can use your created models from Maya in Unity to build levels & environments and there are even plugins that integrate modeling tools into Unity. I'm working with Blender, a freeware modeling software. Your Salvador Dalí clock is really impressive! I'm still struggling with dynamic objects, everything I created feels too static... May I ask which university you are visiting? I'm planning to start to study in the near future and I'm currently on the lookout for universities that teach this kind of stuff.
