I hope noone is going to chop me head off for modelling a portal similar that i’ve seen on inenet just a bit different.
we will chop your head off if you dont list your source of inspiration. 
EDIT:
looks fantastic btw.
sorry, i gravitate to anything with portals lol
It is fruityloops, and Blender itself definately.
Beats with wobbling bass lines, calming pads and bleeding riffs with that magic of percussion along with it all and ofc pretty boobies… a band called KoЯn yet i still don’t know are they real people or robots along with few more and moking weed.
And all of this bright light inside…
Thanks.
This 3D artwork is not finished yet. I Think i may use it’s clipart artwork for choice popup buttons for different locations . But main character would not be able to use them straight away but after completing a chain of quite hard quests and tasks in 1st town let’s say in order to unlock the 2nd portal.
