Thanks for the comments inth, I totally agree with you about the vine being thick but stupidly I had glued it onto the rest of the wall before I realised this and just decided to make the best of a bad situation :)
Wall is well-sculpted for me, but i don't like the grape-vine (or any other plant it is) climbing onto it - it's too thick, and looks unnatural. But the painting is great, so there's 10 from me. Cheers.
