Overall? Not the best.
Hollistically? Much better than many I've seen.
For a first house? Fantastic!
As far as feedback goes: I love modern myself. As far as some vague tips go:
- There is rarely too much green on a build. Turn the biome to jungle, and start plastering leaves and draping them everywhere it would make sense.
- Pick 3-5 materials, and stick with them. My favorite modern block pallet is: Jungle wood planks, snow blocks, ice and glass/glass panes, stone/cobble
You did a good job with protruding surfaces, especially for a first house. So keep that up.
- Finally, remember that minecraft is literally made out of blocks, and a good portion of modern stylings are block shaped ... use this to your advantage! Try to make block shapes the focus of your future builds instead of diagonal lines - since they just don't look as good in minecraft.
Also - beacons are the best for lighting in modern builds, don't know if you used them or not.
