It has been a pleasure watching this scene develop. Thanks for sharing your process and hard-work!
In particular, the wall is amazing - I love the range of color, value, and texture. Its pure eye-candy.
The cobblestone is also very convincing, however, I am curious how it would look if some of the stones near the wall had more lichen (like the wall), and looked less smoothly swept. I think this may already be taking place, but I could imagine it being extended a touch further into the open alley.
Also, I apologize - this feedback could reveal I am just misinterpreting the scenario. Its really looks great as is.
Cool. I almost never worry about giving feedback on deviant art, but your picture was so awesome, I felt inspired to make a suggestion. And it really is just a suggestion. So best wishes - whatever you decide to do!
Ahmad, I have just sent this artwork to our featured gallery. Somehow I missed this jewel of a render, but as soon as I saw it I knew it had to be featured in my group. Needless to say...what an amazing render! Congratulations!
