Critics are always welcome! Thank you for that ;)
You're right, and I noticed that the columns are too large, I'll correct that and the color grading. I like the way you graded the image.
For the AO, there is some but I'll improve that too :p
One thing on the palms, in reality this is not gold... This is just a gold painted plastic that doesn't look good at all XD
I tried a render without the bump and it looks better.
I rushed this image, and I definitely won't do the same mistake next time... I'll post the image soon, with all theses corrections done!
In my opinion, the only way to improve myself fast as an artist is to take critics. So, thank you for that :)
