So, I've got the general concept of the Shattered Lands continent, Tamal, mapped out. However, every time I go into photoshop I manage to condense the space between the North (Rutland, Arbellor, Weland, etc.) and the Midlands (The College, Demat, etc.) even further. What I really want to do is to EXPAND that space while still having a manageable filesize. I've tried increasing the px per inch to get high resolution typing and whatnot going on in those areas, and I've tried expanding my document size from 1000x1000 to 1200x1200 or higher, but my machine just can't handle this sort of thing.
You could make it into pixel art. If that floats your boat, that is, but I think it would reduce file size a bit.
Or cut the big map up in smaller pieces, and work on these separately, however, that would mean going back and forth between maps quite a bit. Which could be tedious.
