this is my first render
honest feedback is appreciated
Wow, for a first render, that is amazing.
There will be one keyword turning back all the time on your learning path towards photorealistic renders (if that is your goal), and that is: variation.
Means that in Blender, everything is perfect (flat, equal, identical, simplified). In real life, there are variations everywhere. To name a few: variations in roughness, albedo values, light (color, intensity), geometry. Also, bevels, DOF, Motion blur help to get more depth and variation. Often, the variations in the variations could use some variations.
