Well, So far I like this OT... But I have some suggestions...
1) You need tutors that speak english well, I can't understand your tutors in the Help Channel, and some of them don't even bother trying to help english speakers
2) Better Map Making
From what I've seen so far, You have mapped barely any caves, all the hunting spots I have seen are in the open and its just tower looking things in the corners of maps, The detail of the maps are fine, just need to make better hunting spots, possibly revamp a couple of the already mapped hunting spots and add on to them (make cave areas)
3) NPC's
Ive noticed that the NPC's are kind of messed up... For the loot buyers, You should make it something like real tibia... Rashid, and Djinn's (Not the exact idea), but when I sell loot the lists are huge and not well organized. Your loot buyers buy anything from Scale armors to rare stuff like Magic Plate armors, I think the NPC's in the starting town should be basic (Buys Scale Armors, Brass Armors, Brass Legs, Plate Armors, Etc.), Nothing rare like Golden Legs or anything, That way its not so confusing when trying to sell loot and the other NPC's that buy rares can be in another town
Also, The creature product NPC doesn't buy all creature products, possibly add more, I find that was the easiest way of making money for promotion was creature products, but a lot of them couldn't be sold, and some of the prices were messed up
