Some things you could do to jazz up your LeTour. Back in the day when that model LeTour was made, black anodized components were very popular. You can do a mock anodizeing with satin or semi-gloss spray paint.

Your bike is a great color. And the black components would give it a vintage cool look. I would paint the chainrings and chainguard. Or remove chainguard altogether. Leave crank arms silver. Get some Weinmanm sidepulls (just a cleaner look than centerpulls) and paint the calipers black. Paint the handlebar stem and seatpost black. Paint the derailleurs black.

Downtube shift levers or barend levers.

Find a set of wheels with black or gray rims. Gum wall tires.

Finish off with white saddle and bar tape.
