improvement in sonic style

I look at one of my sketch books and i saw this pic that i drew in the early 2012 . And seriously this was how i used to draw a "sonic style" (i know it looks more like a furry but back then i had a lot of difficulty drawing that kind of style!)

And the i wanted to how much progress i did with the style had holy cow it's such a huge improvement in one year! And to tell the truth i rarely draw with the sonic style

This one is supposedly to be one of Cutie (my sonic oc) other main (easier to draw) outfit but i chose another one instead. But now that i look at it again i might reconciled it.
