Resurrecting this topic, this is my version of innovation
I think it is very intuitive. Hope you like it
Disclaimer - I'm not an artist but I'll try to share my thoughts clearly.
First impression is this image doesn't feel right. Seems you are trying to capture a process of dim light changing/moving to bright light, but I don't sense movement looking at the card, and the directional arrow serving as a substitute for visual movement doesn't work for me. I like the parts themselves...the candle, the bulb, and background, but am not feeling any are super associative (and thus not necessary to be used) with 'Innovation'. In other words, I wouldn't mind seeing you abandon those icons and starting with a fresh concept.
Unlike other card art you've done that evoke distinct images (i.e. Plate armor), innovation is abstract. Some other card art that fits this style are Parallel Universe, Silence, Mitosis, Osmosis, etc. They evoke an abstract process more so than distinct objects. I'm thinking Innovation might work better in this way, too?
Rewind is an example for me of something that works well for a balance of concrete and abstract. It is sorta in between. It's a spinning object with clear form, but I don't immediately identify that object with anything I personally know (maybe it is some distinct object that I don't know about) and there's a sense of movement. One sort of expects some object to be rewound. If there was a distinct object being 'rewound' (say a cow), the distinct object might distract from the main aspect of the card - the movement aspect of the card mechanic. The cow draws attention to itself when it is not needed. Similarly, that's how I'm feeling about candle + light bulb in your current version.
The current innovation card art has this in-between visual language although the handwatch is clearly identifiable. The fuzzy-motion style obscures the object a bit so it's not so in your face. I don't mind this card art but don't absolutely love it either. I think there's room for an improved interpretation.
I'd be interested to see how you work with a more abstract concept.
