I know nothing about architecture. But you can have a look at job advertisements in these countries (e.g. on stepstone.com) and see what skills are usually required for jobs in your field.

And then, be aware that as a non-EU-citizen, it is extremely hard to get a working permit for any of these countries. An employer who wants to hire you has to justify to the authorities why he doesn't hire an EU resident for the job.

Yeah, I agree with Luis. If you want to get a job offer as an architect you need to focus on the things an architect should be aware of. Because in my view 3D modelling is another field which requires many specific aspects like: modelling, rendering, texturing and many many more. 3D specialists divide into many sub-fields like animators, interior designers, product shooters 

You need to know even the things about photography if you specialize in interior design or product 

It would be interesting to me to hear from you when you make it :)
