Not done any graphics in a lonnng time..

[Kirble]

Just gave that signpost a quick go and not sure about it tbh, it's more colours than I would want to use to be fair, considering the size...any pointers that I'm missing?

[Chompy]

I don't think the gradient effect fits, as it gives a false impression of a light source :o
Or something like that, graphics aren't my area (:

Also, it doesn't look 'flat' enough kinda?

Where as the light source seems right to me since it has a shadow behind the sign. But as with Chompy, graphics aren't my area so I could be totally off my rocker on it.

Ditch the gradient, try to give it some texture,
