My answers will come across as a bit snarky, but I don’t mean them that way. I’m giving you honest feedback.
I have no idea what your objective might be; you haven’t told us. It sure isn’t clear by looking at it.
What concept? There’s a guy listening to music with easily ignored small type telling people to enjoy listening to Spotify. What are you trying to accomplish? What is this — a poster that tells me nothing and provides no particular incentive for me to do anything related to whatever it is the goal of the poster might be? Are you just trying to make pretty pictures or is this composition supposed to accomplish something?
As for legibility, you’ve deliberately compromised the legibility of the message by moving it down the visual hierarchy chain to a step or two below tertiary status. And then you tossed in a gratuitous distracting trick with a musical note serving at a P.
There’s a unity to the composition, but the hierarchy is wrong since the written message is subordinate to everything from the magenta background to the guy in the yellow shirt to the swirling music circling around his head.
No, As far as I can tell, there is no overall goal or objective other than to make a nice-looking composition for no apparent reason other than to fulfill an assignment. Or is the poster supposed to make people want to sign up and listen to Spotify? If the goal was the former, OK, it looks nice. If the goal was the latter, there’s no call to action or incentive that promotes Spotify — unless, of course, there’s something about the guy listening to music that makes people relate to him and want to enjoy music and begin dancing. Again, there’s no obvious concept and no apparent strategy to make this poster accomplish much of anything.
Define the problem better, then approach the problem with a solution that focuses directly on solving the problem. If this is a poster promoting Spotify, the poster needs to do just that, but the message is lost, even if I knew what the message was.
In today’s marketplace from a client’s business perspective?
The composition is nice-looking, but the student apparently doesn’t understand that making something attractive is just the hook used to get the target audience to notice and pay attention before moving them a step closer to whatever the client (in this case Spotify) is hoping to accomplish. In other words, it looks nice but that’s as deep as it goes. There’s no obvious goal and no apparent strategy to achieve whatever the goal might be.
That was an awfully harsh critique, but graphic design is about more than making things look nice. You have artistic talent, which is a great first step, but you need to use that talent and put it to work in ways that go beyond aesthetics.
