Beautiful! The creature in front is so cute

The cracks are passing the limit of the glass...

Good observation, and as a matter of fact I was debating on whether or not to erase those further, thinking the black edging was on the inside of the windows. I think you're right, tho, and I have uploaded the revised version.

an accompanying step by step would really help advance your votes author.. something to think about.. this is a very pretty image and a SBS helps peeps see how the work was done

good luck

Very interesting. Although I usually question borders, given the brightness of the image, the modest black edging makes it stand out more against the standard white pxleyes background. The blending of the two cloud sources in the center seems odd, however. The bright glints on the vents would seem to suggest strong shadows, not nonexistent ones. A hi-res version would be nice. The front vent actually seems like it might have a reflection which is weird (made more so when none of the other vents evince one).

loved the title

Ok, architecture of colosseum is round, but the sunlight that pass through the windows must be all to the same direction.
