I dont feel you have explained your mocks very well and from the few small scraps of information i can find in this thread i'm assuming that these are NOT supposed to be Virtual Reality Studios and you have in fact designed Sets that would be built. (Please correct me if i'm wrong)
Based on my above assertion, regardless of how long this mock took you or its level of originality or the quality of its execution, i cant give you more than 1/5.
The following is for anyone who wants to know my reasons 'Why?' - Also apologies to the OP if not all of what i'm about to say applies to this specific mock because i'm using your thread as a place to dump this neutral-tempered ramble.
There are two types of mocks that are typically submitted to the Gallery; Original Designs, and Recreations.
A Recreation is where a creator is attempting to replicate the original design as closely as possible. Simple as that. I personally rate these based on the scope of their ambition (Title Sequence would rate better than Astons) and how close the execution is to the original. (In the absence of the ability to physically build a Studio Set a computer generated version will suffice.)
Original Designs, are what the designer would do if they were in charge of designing for a particular television property - be it an entire channel or a specific programme. I personally rate these based on originality and execution.
Whilst any original design is limited to the designer's imagination and technical ability, an original mock design is not restricted to the wants and desires of a client, ie; the production team. If the designer is working for themselves they can simply produce whatever design takes their own fancy.
Whether you are producing for a client or for yourself you still have to stick to all of the design rules, conventions and requirements for whatever type of new product it is you are creating.
When designing new graphics for print you need to stick to the correct paper sizes and printable area.
When designing new graphics for Broadcast you need to stick to the correct screen dimensions and safe areas.
When designing for a new construction (or Studio Set) you need to have the dimensions for all the component parts of that construction INCLUDING the dimensions of the space it will occupy.
In the real world, If you dont stick to the correct paper sizes or safe areas or spatial dimensions then your new design is pointless and is unable to be used for its intended purpose.
A new and original mock design should be treated as if it were going to be used in the real world.
Any introduction of fantasy, such as imaginary screen dimensions or fairytale studios will not be tolerated and will guarantee you a bad rating from me.
Creating original graphics for a TV channel or programme of your own invention is stupid IMO. I feel that when there are so many existing programmes and channels for which you can design, why would anyone want to invent something new? You'd have to spend so much time coming up with the entire concept for the programme/channel, useless things like target audience, content, purpose etcetera for what? This is not the place to pitch new ideas for tv shows.
I've probably said most of what i've written here repeatedly over the years in many other threads with various levels of incoherence and 9 times out of 10 it will be ignored. I just had to get this off my chest.
Again, apologies to the OP that not all of what i've said applies to your mock. I'm sure you're intelligent enough to work out which bits are relevent to you.
