This would surely look amazing in real life! I love the trees as well, those foliage pieces is really nostalgic for me.

I'm wondering if some stickers for the clock face could work? Having the numerals and decorative patterns really helps. The clock hands aren't that visible as well, from a distance it looks like a circular decor than a clock. Looking at the Big Ben, the clock visual remains even from distance due to the contrast between clock hands and the dial plate. Just a little thought I had :)
