Well for first attempt, pretty good.
For future ref tho,
Would have put a full tile top of window reveal instead of cut.
On cooker wall u've extended up a full tile, because of extractor obviously,
But u should have mirrored that elsewhere too.
Can't see in corner of window/kettle wall cos of what looks like a music speaker, haha but would have moved window set out left to eliminate small piece on side of window reveal.
U would have had jus one small piece being cut in to boxing left of window.
The fact that u've left boxing un tiled actually looks ok, although not the 'norm!' But then what is nowadays? Haha
In the second pic down, u can see what I mean about cut tile on top of window reveal against line of tiles on cooker wall, it looks lopsided.
None of this is criticism, just observation, it's a good job!
Excellent choice of impact driver too!
