Quick answer .... Yes and No.
Afterall this is scale modelling .... not all details can be produced accurately and sometimes effects are exaggerated to highlight a detail .... drybrushing an example. Yes its a stone wall and looks like a stone wall and will fit nicely into a dio! There are many kits of walls that dont have as much detail or poorer detail.
If you´re personally happy with the wall, you dont have to get approval from anybody ... if it convinces you, thats all that matters.
On the no side of my answer...... this wall appears to be larger stones built on top of one another. In reality a stone wall has lots of smaller stones to support and fill the gaps of the big stones. No way could any height or stability be achieved with big stones built this high alone.
Your answer probably lays somewhere in between both points. Not maybe the perfect answer but my opinion on the matter.
Maybe with some extra detail added like window frames or some rafters of the roof it will be even more convincing. Plus no wall ruins were a single wall. Its possible to build a joint free corner with this method ... another step to improve the effect!
I like the effect you achieved though... did you glue the stones first and then fill in between them? What did you use for filling. The mortar looks very convincing!
