Nice work, keep these things in mind however:

1. If you’re making metallic objects then use gradients to add shine to it by using the base metal colour and adding a lighter variant of the base colour, using plain white works as well but you need more transition than just: base colour to white.

2. Make sure all the letter, numbers etc have equal spacing between them , height and thickness.

3. If trying to make the hollow part of the number 0 or letter o then make sure the colour in the middle is the same as what would be on the outside of the 0 and or o.

4. Make sure the award model (the stick an) is similar size to the base (‘10th’) otherwise the size difference will make it look rushed.
