I tend to agree but he will need to find some royalty free option
I like the illustration used here but I think it would be nice to steer away from these old templates if I’m honest.
The template is made to look like a Hammond box but the curved edges are not really how they look IRL and the scratched texture is over exaggerated. Like it is intended to look realistic but in the end it looks less realistic.
Also I think it would be nice to steer away from knobs and footswitches that are angled. Since some pedals are not angled and no amps are angled, it gives this weird impression that there is perspective only sometimes. It would be more consistent if every plugin looked as though you are looking directly at it with no angle perspective and it would look more like all the plugins exist in the same world
Your work with the images is great though!
I agree, this subtle change makes it much more readable. I think in general, knobs don’t need to have so many fancy details, they can just be a circle with a line really. Although a little bit of style is nice
