A good start.
We assume that Ethiopia has harsh lighting and clear intense skies, so lighting approach acceptable in this case, but usually slight overcast using the excellent Artlantis heliodon gives more complimentary details.
1: color saturation reduced except the sky.
2: foreground cropped to eliminate visual barrier of the curb and sharp corner of planting. Also ugly.
3: Re-framed for more sky.
4: Glazing too clear - add reflections, grime and distortion using shader.
5: try to use ambient light to fill dark shadows - reveal more detail at ground level floor under overhang.
6: foreground planting is weak. Give us a low hedge or fluffy bush, not bright flowers that ravenous local varmints will quickly demolish.
7: surfaces too shiny.
