here’s my thoughts;
you saw a building when you composed the pic; but now that the picture is done it looks too small and disconnected /distracting.
I don’t think though I would just Give up on the building (or at least if you Do- don’t do so without some study and thought)
instead experiment a little, what happens if you bring it into the scene; perhaps Behind the statue/tree. is that something you can envision and draw?
its ultimately what kind of statement you are making; are you seeking to just highlight the vestal virgin or do you want to provide her with a context?
i’m not sure what works and what doesn’t. but analyze the reference photos, and do some thumbnail sketches seems the right process to exploring these thoughts.
I too am a beginner.
and as such I think for myself something that plagues these kinds of changes for me is confidence.
confidence that I could redraw the statue as well; and confidence that I could move things about and not be so enslaved to my reference photos.
I know I need to get over this.
so I’m giving both of us (what I think as) good advise for the future…
BTW; its a beautiful drawing. ty for sharing it.
