i've noticed this in a lot of your designs (and i'm trying to be as constructive and nice as i can) but your subs have not changed at all since your very first one whatsoever. what program are you using? paint shop? i'm sorry, but you should practice some more. a lot of your stuff is scraggly looking &the edges on things are very jagged. just looks like you threw something together and decided it's good enough in your opinion to be subbed.
i hope you don't take this to offense, but if you want good scores &to get something of your's printed, then i say you should slow down and try a littler harder. it's not like there's any rush, i'm sure threadless isn't going anywhere...
About my design
Anyway.
I know this is very simple and that (usually) isn't much liked here.
But I was doodling this today and I thought it would look lovely on a wall, so I figured I might as well.
