That minecraft stuff i uploaded was from years ago. Literally 2011 - 3 years ago.
I dont even make that stuff anymore lol check my new stuff.
Personally i dont like blender, blender is really hit and miss when it comes to rendering. i find Cinema 4D provides flexible rendering techniques that make stuff look extremely beautiful with little effort.
I dont mean to be rude to you, you're obviously new to 3D design in general. but i think you should work a little more on how your own stuff looks before critiquing someone elses.
