the biggest problem… you musta never read the church mouse books by Graham Oakley…
nah, i think the bigggest problem for me is the overall composition. In terms of the actual focus, it takes up not a lot of space, and there’s a lot of other stuff that doesn’t receed into the background enough to let it speak.
Maybe if the Dove was further to the right, and in take off mode (taking off backwards, wings outstretched curved around), maybe the cat in mid pounce, it would of course have more dynamic, and more focus from the rest of what’s going on.
Another blank area (aside of from the right) is the area of floor in front of the action. this is evidently in a Church (or at least to me that’s evident) and you would expect to have some things in the forground, even if it’s only the very blurred side of a bench, or of a pillar, and maybe that’s more of the problem, that the depth has all been flattened out too much, it’s all midground, not much foreground or background.
anyhow, i like the premise of the image, so keep going on it.
