Here's a couple custom WCFs I made. I got a couple of the Goku/ChiChi WCF knockoffs you can get from China for under $10 as a base. The heads were from official WCF figures but had to be modified a bit.
By the way, make sure to host the images on IMGUR or somewhere else. I regularly have to delete DBF's attachments when they get full (even though I usually exclude the custom figure topics), but if you host the images yourself, it'll ensure they are here forever.
