architectural renderings service and service tax

[3dsmaxed]

hI ALL

I AM A FREELANCER artist from north india
what i want to know here is that does architectural visualizations come under the service tax belt?
we are basically doing architectural 3d renderings and animations and sometimes also cad conversions for 2d drawings
fields realted to computer softwares are not liable to service tax in most of the cases. Do we come under the service tax belt?

Looking for assured answers. Maybe people already dealing with this can give better suggestions from their CA's

thanks
