I haven't seen it, but here's what I get from that still:
- The freaky logo and dragon dog imply that paranormal activity is one of the main themes of the show. That's up my alley. It's the sort of thing I'd watch.
- They're on a stage with rock band equipment, which means they're into that subculture.
- The dog looks like the star of the show. It's in the center, it's expressive, and the way it's looking at the bug invokes a wonderment at nature, the kind of thing that good anime does well.
- The girl looks like a generic 2000s Western cartoon and could be Instantly Forgettable unless she's written well enough to become her own standout character. Her color scheme matches the background and she fades into it. I can't tell what she is holding, and it's hard to tell whether she is sneering or if she is supposed to be smiling. The eyebrows don't match a sneer and seem to be way out of place.
- There is some attention to detail in the lighting and shading of the music equipment. It's a good sign when an art studio goes this extra step. It shows that they want to produce a good work.
After watching the pilot:
- The girl is the everygirl in a team of weirdos. That's a good person to make the MC.
- The dog is definitely the star of the show. It has a likeable personality, and they did a good job animating it.
- They're all in a traveling rock band. That's a good excuse to move to different locations for new stories, and we can expect that music acts will be a part of the show.
- The bandmates have self-defining personality traits that can play off of one another or be the basis of new stories, but none of them stand out as exceptionally interesting.
- The main thing it has going for it is the extra effort that they put into making the pilot look good, particularly showing off what they can do with the dog's animation.
- It has potential. Whether it will be good or not depends on the writing.
- Whoever animated the dog deserves a job in a cartoon studio somewhere.
So there's one anon's overanalysis. YMMV.
