A lot of romhacks tend to make things really spaced apart from each other because it doesn't look that bad in the editor, but it ends up looking really wrong in game.
Your maps don't really have that problem though from what I can see and it's normal for a desert to feel empty, but what the player would see entering the oasis is something like pic related.
Also kinda unrelated, but I think palm trees would fit better thematically in a desert oasis.
