A featured track usually has a ride of at least 30 seconds and high quality or lots of detail. Those tracks just aren’t big enough. But you do have potential and if you work really hard on one I can see you getting a feat. RAPPERJACK

Apocolypse I think you should try making a track of the Victoria falls, or something like that with a lot of vegetation. It is harder to detail than most things, but you could just go for simple, clean lines and a whole lot of it. Another specific recommendation I have is to draw some famous building/painting. Again, hard, but worth it in the end.
