I think the tires are a huge improvement. I'd maybe go with a black saddle instead of more yellow. So its a Celeste - Black - Yellow bike instead of Celeste - Yellow - Black. Know what I mean? Part of me wishes the bar tape was black, and instead the yellow was kept to smaller accents, like straps or brake components. I like the yellow with the celeste but in large portions like that bar tape it starts to clash a little.
