Thank for the suggestions.
1 - I made the iron rings and a handle to the bucket and now I think it's finished:
old/new
2 - I made another style of hoe and I think it's good, but let me know if there's something wrong or something that can be improved to it:
old/new
3 - I also made some other little changes on the axe and shovel:
Just a better AA on the axe's edge, and shovel's scoop, also a little change to shovel's handle to make it look more centered.
P.S.: I'll polish the contour of the axe and shovel, these black lines are not good now that I've made the hoe with no black pixels.
New grade of tools:
