I think you're being a bit too hard on yourself, you've made some great improvements and your work was already solid to begin with. Your figure work in particular is very well done, drawn and painted.

Developing your character designs further should be simple enough for you as you're already solid with your figure works, so I'm sure you can easily come up with some more complex designs if that's the route you'd like to take. Keep up the great work!
