I love #4 and #5, they are amazing!
Not bad. I think the backgrounds on a few of them could have a bit more to them, but like you said they are old.
I like #5 the most, good work.
duble oozie FTW!
its nice work
try not to over stretch the render and it will be good
I like the third one. Plus the wallpaper is lovely
The colours of the second one could have been better.
But still good job bro
