Need Some Advice

I had an injury to my right hand which means I've had to give up my day job for a while (I more or less cut my thumb off with a saw, re-attached fully now!). As such I have no income, so looking for a few passive ways to earn some to pay the rent!

I submitted the above to ThemeForest but got shot down. The resulting reply was that "it needed more polish" and "doesn't feel premium enough". It was a bit of a blow as it was my first attempt in a while and I spent many, many days and nights pouring over it trying to get it right.

If anyone could offer any advice as to how to improve and work on it, I'd be very happy to hear it as I'm desperate to start selling a few bits and bobs at the moment!

Thanks,
Dan
