Just looking to get a little feedback regarding my artist's first icons for WorldAlpha. You can find them in the DevBlog here:

Any feedback positive or negative is appreciated. Thanks.

The perspective issues bother me, especially on the car, as someone else commented in your link. I don't think it's just noticeable by artists (although I consider myself one.)
I'd like to see it in it's final setting though, and not just as separate icons. Might have a certain charm if everything is just slightly wonky.
Either have your artist correct the issues, or exaggerate the wonkiness (that's a technical term) so that it won't be mistaken for laziness or being an amateur.

I agree. Me-thinks the car is a bit out of place seeing as it is really stylized and the other icons have a more realistic and not warped look to them.

Depending on how serious you want the game as a whole, but from what I gathered from your site, I'd drop the wonkiness (yep, totally legit term. ) to the car icon and fiddle around with the perspective and color palette of the others.
It isn't too noticeable with the other icons, but it does make it feel just kinda off. Like they aren't real.

I'm not saying go hyper-realistic, but they just don't seem to fit the aesthetic of the other stuff I saw on the site, so it makes a bit of a barrier for the player to slightly chip away at the suspension of disbelief.

Hope it helped.
