It's probably because the Art mods don't think your art is good enough.
It's not because you don't submit something regularly.
Your current art is quite good but is lacking a bit.
Use thicker lines on the sketches and put a bit more detail into the flash drawing and you should stay scouted.
PS: being un-scouted is called being castrated.
