After all these years, I still haven’t figured out how to draw his feet…
You might be referring to just nailing down a process to drawing them, but I think you've got the concept of his feet down perfectly, and I've never noticed anything wrong with the shape. They look pretty accurate to me.
Those of you who follow me on either Tumblr or deviantArt will know this already, but for the past two or so weeks I did something I've never done before and took art requests -- specifically, Bomberman-themed requests where I drew either people's OCs/bombersonas or canon characters! Here's a preview of all the ones I did on deviantArt.
The request announcement has the links to the full versions if you're interested. Artworks are listed in reverse order from the compilation, i.e. guess who just screenshotted her dA gallery and stitched it all together in Photoshop.
I'll put together a Tumblr one for the sake of completion when I'm not so cheesebrained.
