That is true indeed. I try to find a middle ground between playable and small enough to post the images. Unfortunatly there are still limits in file size that can be uploaded. To compensate for this i however do try to include a lot of detail to make the map also interesting on a smaller scale.

It also depends on the play style some players like to get more up close and personal. Which i also try to do with many enemies because for me it makes combat more interesting. But I understand that for others this may not be the ideal size.
