Good is...? Redeveloping the 'nostalgia' brand

For the logo workshop, I devised a logo based on the word, optimism. However, the imagery had no direct link to nostalgia (as seen below). As I am intending to brand and effectively package nostalgia into a product, I wanted the logo to consist solely of this word.

Optimism logo

Here I used the 'glass half full' imagery to reflect optimism whereas this would not be as effective with nostalgia. The shadow below gives the impression it is on the surface and sits above the type.

Some initial design ideas

As nostalgia is a thought process, my immediate design ideas consisted of thought bubbles and how this could form the imagery in the logo.

As I will be creating a nostalgia pack centered around the five primary senses, I also looked at how I could incorporate this into the logo. I used simple shapes to form a pentagon referencing the 'five' senses. This idea could be altered to reference each sense by having one of the 5 shapes highlighted - this could then be applied to the relevant products.
