Some deadlines are pretty tight in this field that's a given... From the sounds of it you might have bit off a little to much for your level of experience, espeacially if you only been using maya for 6 months thats quite a load of work.

The thing about the 3D field and Maya is it takes time to build up your speed and work flow to opptomize how fast you can produce a project.

To be honest 2 weeks for that project seems a bit small, considering you have to do every aspect of it.

Hope you make it..
