My experience- I've done a few 3D designs in Sketchupand Fusion 360. Prints were done in PLA on a FDM and SLA machine that I have access to.  Generally I am quite happy with the results. Now the description of my question. 

I would like to create a 3D model of the house and yard that my wife grew up in, print it in miniature then assemble it into a snow globe to be given as a Christmas present. Quite a challenge I expect. The final thing does not have to be exact but a fair representation so that she can actually tell that it's her house.  Some specific questions:

1. The house is brick, would the brick texture actually be noticeable on the printed model if it is say only 1 to 1.5" on a side with either SLA or FDM? 
2. Same for roof shingles?
3. Or should I just rely on adding these details artistically in the painting process  ( I will have to find an artist to do all that ) 
4. Thought on trees/ bushes?  Again I hope to rely on artistic license when designing these parts. 
5. Thoughts on software - which would be best to design in?  It has to be free or lie $$$  since I am not doing this professionally and don't have the $$$ to buy 3D software?  Someone suggested Blender. Fusion 360, Sketchup.  Others?
6. Thoughts on best printing method ?

A lot of questions I know and I truly appreciate any feedback on any of this.
