Some things i see here that need work, I'm not saying these too be mean but too be a nice friend
- This shield is kinda the opposite of yours due too yours having the metal in the middle and the linked icon has the metal on the outside of it.
- But the linked icon i gave you gives a different angle as yours is somewhat 2d, which is find but 2d image needs a lot of detail too give that 3d effect too them.
- Also, the yellow circle you have there seems pale, I'm not sure if its wood or just a object around the metal shield but maybe add a wooden texture towards it? And, the metal/gray part is overlapping each other on the top left of it as i can see.
- All together i think it would be a wonderful icon if you fix the angle, fix the yellow object around the shield too maybe a brownish wooden texture? and then fix that overlapping on the top left. Also maybe a small background color? your choice.
