No problem, and good to see that you are willing to take some criticism to often people only want to hear what is good rather than what needs improvement. If you can take that advice and the words of the critics you have already fought half the battle to getting this out there.
If I could offer further words of advice develop the the cultures and then the world, after all before mankind left the first valley they already had their own culture. also each culture should reflect the area that they live, not be cliche and have the swamp people and the desert people but to have ideas and clothing that reflect the life they live. Also just think about how many things/places are named after people in real life don't be afraid to have places named after ancient kings and warlords. They don't even need to be developed simply mentioned in passing to give the world a sense of history.
Good luck and I'll keep my eyes on this thread to offer my help.
