Unfortunately your sky is overprocessed, causing pixelation. Really good idea here, great composition. Why did you overprocess it like you did?
p.s. I think that lion is so old he's losing his teeth.
The shot seems very high key, yet the sky is quite grainy. It looks as if the picture was shot at dusk, and a fill flash was used. Perhaps using a longer shutter speed with a tripod would give better results.
I like this eye catching shot but think the crop could be improved.
The lion is so centered and the bottom is not cropped evenly. We could use less of the left side and more to the right to add balance and keep the tower from looking so jammed in there. I see a lot of noise in the sky.
