I wouldn't care less about what people think, except I'd like to sell my work someday. It's sad to know that to sell, I'd have to dumb down my art. From what I can see, people like nothing besides empty spaces, high resolutions, and straight ramps. It's a boring way to draw!
Relax.
You're making large assumptions over such a small poll of 10 people.
Instead of trying to understand what you consider negative tastes of others, try to understand how they can be used (or the opposite of what they are) in positive ways in your own art.
Helm makes good points that there is more to these images than purely pixel tech.
Games have many properties that will influence how people think about them and can alter what their opinion of each property is.
"The art is so amazing that the mediocre gameplay is worth it".
"The game play is so good that the crappy art is kind of charming".
That's why its good to have a team of diversified people for a game project.
One to focus on the expertise of the art, another to code features and functionality, another to make creative levels within limitations, maximize flow and reward, etc etc.
Also showing videos instead of stills might get completely different reactions.
Art in motion has a different feel.
The thought of getting to PPD's level one day

I'm just some dude.
Don't worry about such things.
Just keep a clear mind, be humble, pace yourself, try new things, learn, make a plan, draw stuff and have fun.
only to have the audience go "bleah, why is the girl blue?! I'm playing something else instead!" is a little disheartening to me! Not every game should look like Farmville!
If you work at a studio you may not always have complete input on your work. You could be an asset artist for a concept artist, taking their designs and implementing them. Or you might have and even more specific job like only animation. This can pay good money and be a great learning experience.
If you'd rather do things on your own, find a way to go indie or get properly funded. You'll have more work but also more control. I'd still recommend having a small team.
Tell me how it is destructive?
Alex, I'd be happy to openly discuss this. What should we call the thread?
