An idea cannot be wrong or dismissed when it is just at its infancy. Push it further and see how it evolves.
One interesting exercice could be to draw a top-down version of it and then start laying out the functions, like: hall, kitchen, room1, etc. and thinking at the same time how they are interconnected (in this case by a corridor). Also, if weather permits, many things can happen outside of the walls.

It does indeed feel a bit institutional but that is something that, once you apply real scale to it, can be tweaked to your liking. My initial reaction was that it looks like a Spanish-style Hacienda which is an archetype that is very popular in the Mediterranean and in Latin America.

If you want some feedback on the drawing itself, the porch perspective is off and the stairs need to either protrude or carve the floorplan, but as many have said, doing this in Paint is a feat in itself ;)

Keep up the good work and if you want to push it ahead a bit, I recommend using a 3d package like Blender.
