Thanks for noticing. yes i did use the grass essentials (because i helped in the trailer and i wanted to promote it) and yes i did use Pro-Lighting Skies (because i wanted to promote and test it) and yes the axe looks really poor (no excuse)
as for what i made myself… everything but the grass and sky. i made the rocks, logs, ivy and everything really.
i made it in about 3 hours just to show off those products. thanks for your feed back.
if you would like to see more work that i did myself feel free to check out my newest architecture render here: https://www.artstation.com/artwork/lounge-room
also you can read about it in 3D artist magazine issue #83
hope that clears everything up
