The Toughest Little Colts In Town

The pony versions of my characters Kenta and Sasuke, the Honda Brothers return! Four years ago I began doing MLP related art and the first one I did was of my characters as ponies. I feel like I've come a long way since then in terms of drawing ponies (real or the My Little variety) and while I still like my first drawing, I think this one came out a lot better and was closer to how I wanted the pony versions of my characters to look in the first place. Please let me know what you think. Tips and suggestions, as always, are welcome.
