Nice! I see a big improvement with diglett and dratini there. Only thing I would suggest is to make the lineart smoother. Or, if you're having difficulty with smooth lineart, then maybe try doing a rough border, but maybe with action lines, or make it look really accented and jagged for the lineart. Whichever works for you, just try and find a style and don't be afraid to explore with different things!
I hope my critique and advice helped you. Keep up the great work man! For a simple yet effective pokemon I would try snivy, since smooth and jagged lines could work for it either way. :D
