Hi I'm Jacopo Italian 3D and Digital artist.
I'm specialized in architecture visualization and furniture still life, but also in 3D still life of little objects like jewelry I can do something great.
My objective is reach the absolute photorealism on my works and I work hard every day with passion.
My software is Cinema4D+vray, one of the best program for the CG.
I think it's possible complete your request in about 2/3 days when the final version of the image will be approved, for all the 50 images (25+25 right?) and if you want I can make little video of the ring that turns on itself.
My price is slightly higher than the other offers but the result is guaranteed (however it is negotiable), You can look at my portfolio for a demonstration, the final job are absolutely professional and my service includes a high level of customization, ALL THE IMAGES IN PORTFOLIO ARE COMPLETELY MADE IN 3D SOFTWARE.
I hope Consider my offer, I am available for any questions to my mail.
Best regards
JF
