First Time poster some of my props

Like the title says this is really my first time posting some of my work on here. I've been skulking around on this site for a couple years now and this is the first time I think my work is good enough to post. Let me know what you think or if you have any tips. My mom was a little goofy in the foam armor pics.

 

I loved Plants vs. Zombies, and the sphere is interesting...is it hollow ?

 

Thanks, I posted a few more pics. The sphere isn't hollow its Styrofoam that I burned the grooves in to make it look like the orb from guardians of the galaxy.

 

Nice work!
