TBH, it looks okay, and I'm sure the next will look even better now that you have the things the others have already said in mind

Also, though it might be the lighting or the angle of the photo, you might have used to much water in your grout, or when washing off. I
think I can see some colour differances, but that's probably just nitpicking on my part.
Did you remove the skirting prior to tiling? I'd recommend doing that, as you don't have to silicone then, unless you really really want to, or if it's a proper bathroom. Looks neater, too
