It just looks completely off knowing there are actual renders next to it.
#Handcar icon consistency
wheat gazelle
sinful dome
Solution: make all of the items sprites
Pixelate everything
Pixel locometal
Pixel train station
Pixel conductors
marble rivet
it was previously a item model
but it's large size makes it not look great as a item model
jagged siren
ig also since its an entity and not a block
wheat gazelle
Couldn't it be scaled down?
lyric pulsar
it's also a vehicle like a boat or a minecart
wheat gazelle
Those are far easier to distinct and recognise what they are. Same can’t be said for the handcar. That and, a lot of mods don’t always follow that rule either.

I don't see why it wouldn't be any less recognizable then the boat & minecart
and even tho a lot of mods don't follow that rule, it doesn't means that this mod can't follow it
wheat gazelle
Well issue is, this isn’t a boat nor a minecart. The main point is that at its current state, it’s an odd thing with its pixel art not doing it a favour of distinction over what it actually is, since there’s hardly information to gather what that is and is therefore, less distinctive and out of place especially for what it is. Even this server has the logo too, since I feel not that many people would recognise what the logo is if we had used the in-game icon too.
jagged siren
the server uses the model, as the create one uses the wrench model.. as do most discord servers of create addons
there is always the option to rework the icon art itself
hoary path
I think that a bit higher res of the pixel art would be good. It would keep the style while giving it (hopefully?) more recognisable at glance detail.

you don't really want to make item textures at resolutions other than 16x16
marble rivet
could do mixels
